Gawd Daaaaayum!!! My man! I predicted 10.999 I was close! Hella impressed with what you've accomplished! I'm trying to get back in the groove net year. Keep up the great work and content!
@@greazedlightninggarage6768 Thanks brother! Much appreciated. The air was really good that day but I think there might be a little left in her. We’ll find out next year. I would love to see you get your Duster on a track with the kind of DAs we have here.
Yes you are correct. Sometimes pushing the converter is the way to go, sometimes lightly pushing it and letting it flash works better. You'll have to try both on the same day to see which works better for you. Your car is awesome. Love watching this.
I'm considering a Duster/Dart LA build in the near future. I might have to pick your brain for some advice when the time comes. Everything looks awesome bro.
When I raced my Super Stock Duster 340 back in the 70s I found the collector extension to be critical for my best times. We never got 60ft times back then. Just quarter mile. Great times for sure!
@Duster_Garage It's not been being worked on. On the back burner I guess. BondoBilly had a heart attack two weeks ago, he is ok now. He is in the recovery phase. 🙏 Thanks for asking. 👍🇺🇸👍
@@BigfootsnMopars Thanks Mark. She really has been making some big steps this year. So far they haven’t said anything about a roll bar, but I only run in test and tune.
Congratulations! Straight through mufflers are usually better flowing than chamber muffler’s. I don’t think you will pick up much if anything with the single plane. MAN I’m surprised the track didn’t bounce you with that ET and no bar. Congrats again!
I seriously doubt if you'll pick up much, if any, with the M1. Unless you shifting over 6K I think your times may drop. The Air Gap matches most single planes up to about 6000-6300 from what I've read. I budget built my 414 stroker with Air Gap, Eagle SIR rods, Keith Black hypereutectic pistons, Mopar cast 4" crank. Made 460hp/510 torque. Peaks at only 5400. I purchased the Trick Flows as well. My plan is to switch to .600 lift hydraulic roller, up the compression to 11:5.1 forged pistons, Scat rods, maybe switch to a forged crank. I have a Victor 340 I may use. I've seen the Air Gap support 577hp/557 torque in one build. The most I've seen. That's the kind of power I hope to make. Good luck!
@@ragingbull3406 I think you may be right about the intake swap. The Air gap works really well for the power level I’m at but I gotta give the M1 a shot. I do shift at 6400-6500 rpm. Good luck with your build. I think the power level you’re looking for is very attainable with those heads.
It is great to see the progress. I just picked up a yellow 72 with a 408 and Edelbrock heads. It's a monster. I was told it did 10.80s. With your Trick flows it would be even better. I'm actually going the opposite direction, trying to make it a little more streetable.
Good job! I’ve got no ideas on the exhaust, so it must have been the exhaust! The intake test will be interesting, not sure on that either but, my guess is you might be wanting some more stall to see the benefits? Anyway, looking forward to it!
@ I forgot to comment about the end of the video with the new manifold, I think a lot of of us are anxious to see what that does. I talked to my engine builder, the engine really never made as much power as it should have he said. He said he’s going to try a custom ground cam, and thinner head gaskets. He’s only charging me $1000 to go completely through the engine and clean everything to rebuild it. Just waiting for a chance to drop it off at his house, he is about an hour and a half north of my house. for now I just got the tired other big block in the car, my wife and others think I was crazy going through all that trouble to stuff another motor in there that I had instead of just waiting for the new one to get back. But I get anxiety when my car is apart like that for long period of time lol
@@Duster_Garage I wanted to say what’s up, and announce some good news. I just bought a 440 I’m gonna put that in the car now, it’s out of a 12 second dart, he’s gonna refresh the engine first. But I just paid for it so I’ll be now having to buy headers a new distributor new intake, but this is good news. Hope your duster is running awesome still. I can’t wait to post a new video and see your new videos coming up.
@@maximuswedgie5149 That’s awesome buddy! A 440 is going to be a torque monster. Should be a riot to drive on the street. Can’t wait to see how she runs.
MY GUY!!! 1.51-60ft and 11.15 @119?! Holy Crap!! The guys that have been around for a minute, know the leaps and bounds you’ve made on her. And let me tell you, for us old timers that have made a pass or two, that first run felt different through the video. Any seasoned racer KNEW that pass was going to be a monster. She left the line with her pants on fire and caught full blaze at the 1/4 track mark. You’re going to be really close to getting that sweet thing into the 10’s. Which is something we gotta talk about…you and I had talked a bit about a medium sized turbo for her. The thought, of course, is that with the torque you’re putting down & the trans-brake, you don’t even need a 2-step to launch on the bump. You can just get up on her usual launch RPM….She’ll spool a 68mm turbo up by 200ft and that sweet yellow lady will put her ass to the track and DIG, BABY, DIG. Possibly pulling those heads and putting titanium valve seats & boost rings in it, and a 200hp of NOS? Just some ideas…anyhow, CONGRATS ON THE PERSONAL BEST!!!
@@NostraThomas25 Hell yea! She is having the best year of her life. I know you would like to see me boost her but that stock bottom end is about at its limit already. That’s the big reason I want to build a stroker. A forged crank, h beam rods and forged pistons would handle just about anything I can throw at it. Btw, she doesn’t have a trans brake. She just launches that hard flashing the converter from 1300 rpm.
Taking the exhaust off mine did help and I am just running the header extensions about 14 inches long! car went 7.04 with extra 100 lbs in trunk! Pulled it out went 6.90 next time out right off trailer, took 2 degrees out of it and 1 jet in secondary and went 6.86! You are chipping away at yours for sure! We cut .600 off mine in about 7 passes! Now we got a legit 10 sec street car 😊
@@377PoisonDART4 Hell yeah! That’s awesome! I think there’s still a lot left in that 377. I’ve been chipping away at my 360 for 15 years. I don’t think there’s much left in her. But I’m gonna squeeze her a little more. 😂
@@moparsareeverything1980 Thanks Mike. Slowly but surely I’m making progress on her. My goal is to eventually have a reliable, pump gas, 10 second small block street car.
@@moparsareeverything1980 That first 415 you had in the Barracuda ran mid 10s? How big of a solid roller cam is in that engine, if you don’t mind me asking?
@@Duster_Garage Yeah it ran 10.48@ 126 and that was first year racing and owning the car so I didn't know much about tuning and tweaking on them yet. I will find the specs tomorrow for you and give them to you. I ran it on 91 octane on the street and I usually would put 110 in it at the track but obviously it didn't really need that.
Awesome! Knocking on ten seconds door! What a great end of the season. 😃👍 The progress is coming along awesome. With the couple of variables that you mentioned - do one at a time. Perhaps the camshaft first (even though the intake has to come off) ... See how the car reacts to the camshaft. With more lift the valves should be open longer. Then give the intake a try. Best of luck to you 😉
Saw ya Saturday just didn’t get a chance to say hi. You’re right, the place was packed. I end up getting 4 runs in but had to stay to the very end. I run a m1 too. Just the fuel injected model. Most likely will like higher rpm
Excellent Duster Bro, 11 seconds is no slouch time man, my 2021 Chally Scat runs 11s and it will put your head in the back seat....lol The DA is always your friend, or enemy 😊
@@vinnyd4166 Thanks buddy, I appreciate the compliment. Both my Dusters have a standard volume Melling m-72 oil pump. My yellow Duster has a Kevko oil pan and uses the Kevko pickup tube. The white Duster has a stock center sump pan and pick up.
Those are some impressive times in a quarter mile.. I think a 3000 Stall converter would help..a set 3.91 Gears. Again, that's a nice 340 duster or dart. Great video. Keep up the good work until I see you in the next video...👍🙂🙏🏻
@@davidlinck7459 Thanks buddy. She does already have a 4000 stall converter and 4.10 gears. Hopefully the next video will be a road test with the single plane intake manifold. 🤞
Great Job! The exhaust is definitely letting it breathe, you can hear it really coming to life on the big end. You’re already past the point where the M1 will make more power. I like the higher lift cam (along with the M1!) you mentioned, too, but even more so with a set of 4.56 gears. But getting to where you’re at now is damn impressive with an all steel street car.
Congratulations! I think the single plane will benefit you. In my experience, the loss in bottom end from single plane intake is only really a thing on stock engines. I just found your channel, so I better get caught up!
@Duster_Garage Absolutely! I have about a 350ish hp 360 with 4.30s and a stock converter in my Duster. I run an Edelbrock Torker 2 single plane intake and it is definitely not soft on the bottom end. Traction is a big problem for me now. My suspension is same as yours other than I have shit shocks. The Nitto Drag Radials i use are part of my problem too. I think I'll make a video outlining exactly where I am at with my car. I saw you did a year or so ago. My best is 13.30 at 104.
I commented yesterday but for some reason its gone today 🤷...Anyway...Congrats on the new PB!! She was running great! Getting rid of the chambered mufflers helped for sure! I know from past experience on that! And the weight savings also,great 60ft! Im pretty sure you were making more than 450 hp that day,unless your car is a lot lighter than i thought lol...My car is 3550 lbs with me in it and i ran 6.97 last week,the wallace race calculator says that it was making 517 hp (at the crank) that day,as far as the Intake goes,in my opinion i think if you go with a bigger cam it will help for sure,especially with the heads you have on it now,not sure that it will help much with your set up now but im definitely no expert lol. Its definitely worth trying it tho,always great to get realtime results with changes,and sometimes things really surprise ya that most say wont work! Keep it up man,the car is impressive as always! 👍
@@RT211Racing TH-cam is screwy with the comments sometimes. Sometimes I don’t even get ones then a month later they show up. Anyway. Thanks, I was pleased with how she ran. I would have liked to hit a 6 second 1/8th though. There’s always next year.
@Duster_Garage You will get it man! If not in the early spring then in the late fall,if the DA woulda been at 0 ft sea level that day you would have probably gotten that 6 second 1/8th! Air makes such a huge difference! My car runs almost 3 tenths difference between the summer and fall lol
Good to see you out one last time before the season ended. I've actually been extremely busy on my 73 Dart and was able to go a personal best in E/T and mph. 10.86 @ 122 in the quarter and 6.86 @ 99.98 on 1/8 ml looking to going into the 9s next season. Have a great off season talk to you soon. Dont be afraid to just run 12" collecter pipes open with no muffler so it can breathe. ✌️ nice improvement 👍
Oh it will see the 9s for sure. Just getting started and once I get back into it next season I will be hitting that little red button on the steering wheel 😂.
Awesome a-body in every way. Built right. Hooks well. Wonder what a loose converter and slightly deeper gears would do to ET. Seems like chassis can handle it. But sounds like motor is near redline at 1320’. Cool stuff.
@@mopartony7953 Thanks buddy. She works pretty good. I was thinking about an 8” converter in the future but the 10” in there now does flash to a little over 4k RPMs. And you are right, the shift light (6400rpm) comes on just after the traps. So I don’t think I want to do a gear change. Plus I drive it 100 mile round trip to the track.
@Duster_Garage love it man...I'm the same way ss springs...why? Cuz its Mopar m1 why? Cuz its Mopar....you have all the goodies to let the m1 eat...interesting enough you have the m1 that takes the little magnum thermostat housing. Anyways man good video and as always you have 1 nausty duster see ya brother🙃
@@Robertadkins-h9c it is the small thermostat housing flang. And the straight thermostat bypass hose fitting like a magnum. Is yours a spread bore flang too? And did you have to gasket match the ports? These are kinda small.
@Duster_Garage yea mine is spread bore flange as well. When I ported the heads I did port the intake to match. But if memory serves me right stock eddies and stock m1 was a nice match to each other neither one needing ported to match each other. But I'm not sure about TF heads. I know hunter got the track 1 intake with the tf heads and yea trick flow track 1 intake needed quite a bit of clean up work to match...which i found strange it's there intake and heads you'd figure the ports would be the same size lol
@Duster_Garage as far as the m1 intake pound for pound inch for inch is very hard to beat. They do need cleaned up under the carb hat you'll feel sharp edge under the carb hat where it transitions into runners basically the roof of the intake needs some fine tunning and smoothing from bottom of carb hat to runners other then that my opinion best small Chrysler intake ever made. Especially for something 400hp to 550hp
Bravo DGI'd say it's about 40 lbs lighter without the exhaust. The H pipes are beneficial tho. Hmm idk Brother. How's she sound with the Bullet mufflers?? Maybe give us a Soundbite in the ol driveway eh✌️🤠🌵👽🌾
@@hausf.kartreit1111 Thanks brother! You’re on the money about the weight of the exhaust. It was 36 lbs lighter than the collector extensions. They sound good but they’re loud as hell. I should do a comparison video of the two exhaust.
Good for u man👍The 18" collector ext seems to be the majic number for any engine.Engine masters showed like 40-60 hp with them.Id like to see a trans brake on that car👍
@@HermanMunster-o2j Thank you. I saw that Engine Masters episode, that’s why I made those extensions. Lol. Not sure about the brake, but I won’t rule it out.
💪🏻 Man! That's awesome! I'm interested in the M1 comparison as well, keep us postal on that! The camshaft you are running. I really like that grind, I don't think you would pick up anything with the comp. A friend of mine ran the same grind in a pump gas 440. He went mid 11.20s with unported Factory iron heads and 11.0s with a bowl port. Really nice cam it's a big pity they're not made anymore
@@timosracecars Thanks brother. It is a nice cam. And it has done really well for me. I hear ya, it’s like Mopar doesn’t make anything for the old stuff anymore. Shame.
Impressive gains by removing the exhaust. I know many years back a racer had a 68 dart with a 440 that ran a 3 inch h-pipe with flow masters. dropped the exhaust and put collector extensions on and it picked up 3 tenths. 10.30 to 10.00 flat. Not at all surprised at all at the gain you got. Your car 60's really well with a dual plane, The only thing i am unsure of is what your converter flashes at. If your converter is loose enough you might not lose much or if any in your 60 ft and just make more power up top. Certainly there could be maybe another .10th in the combination with the m1 intake but will have to test and see. With the new short block you are planning on building, Have you considered going forced induction?. I bet for the same price or less then the short block your building you could probably order a procharger kit with your current short block and make significantly more power and still keep it very street friendly. Those trickflow heads will cap out just shy of 600 HP so i believe the bigger short block wont be of much benefit vs a procharged setup. Enjoying the content as you progress with your combination looking forward to more content keep up the good work.
@@Mestoc I’m thinking the same as you about the intake. My converter flashes to about 4000 rpm and my low gear set in the trans makes first gear like it has 4.56 out back. Hopefully enough to cover up any loss of torque. As far as supercharging this engine. The factory cast crank and stock rods won’t handle it. Especially the rods.
That is a nice jump in MPH, hope next year is even better :) I was planning for 390 my 318 or 408 a 360.. but might just go 360.. that thing runs great. BTW, kinda surprised how small your cam is with that speed.. although i don't know the duration.. i think i overcammed my 318 .525/.532 on 109.. sounds and runs good though.
Forgive my MOPAR ignorance due to only having had cars with SBC/BBC, is the sump in the front of the oil pan like 440's and HEMI'S? If it is, how do you deal with oil starvation issues? As to your car, 11.21 speaks for itself. Well done SIR!!!!
@@396375a It’s all good brother. Chevy, Ford, Mopar, we’re all car guys. The oil pan I have is a center sump. It is a Kevko pan, extra quart, trap doors, baffles and a crank scrapper. Works good. And actually the best run that day was an 11.15@119mph. She does ok for a little pump gas street car.
I run a a strip dominator on my 360 i had one on a 340 really woke it up 284 484 speed pro pistons no head work 3.91 3700 pounds 13.40 88 degrees Milan drag 77 aspen tank awesome job your on it
Well like my brothers two cars, One is a dart, other a duster, both 340 cars with very simular cams and both have matching exhaust, they both have cutouts. The duster has stock iron heads, the dart has alluminum more open flow heads. They both sound great with cutouts open but the duster does not perform as well with them open but the dart with the alluminum heads loves the cutout open and performs excellant
What is the weight savings w/collector extensions and shorty bullets versus exhaust turndowns before rearend? Those collector extensions, bullet mufflers, weight savings, and good air all contributed to those two great runs. The 190cc size of TF heads are ideal for 3.58in stroke and rod ratio of stock 360. 119mph? Wicked!
usually you can feel engine pulling harder as it nears Peak torque. and yousaid that in video , lol So the other trick was said that paint the Collector extensions and where the Paint stops after racing is ideal length.what is your Stall flashed too? I have seen a closer set up to yours he was at 3800 Rpm with a challenger. BTW great work with that combination. i only seen 11:5 as best passes with a Duster and that camshaft
@@Duster_Garage Nice good stall now , I tried the 340 with 1 inch spacer on the 340 Vic Jr and ports are awful mismatch. I would think if the M-1 makes more power with your combination . then To Purchase the track Heat by TFS i got one and it is almost perfect port matched to Gasket and my TFS Heads, all should fit nicely under the hood. I recommend a video on a Dyno test , This shop has many tests if you have not seen yet i will share it.th-cam.com/video/dPIJib5CWTE/w-d-xo.htmlsi=H8aNeOEsOCoFIFn8
Congrats on the new best. Your Mopar sounds real good and yes the new exhaust seems a good bet on the top end gains. I know you are experimenting with the manifold and maybe cam after that. Do you already have the small diameter “6 cylinder” torsion bars? If not be a good experiment to swap those to see if you gain on your 60’.
@@Ridendrty thank brother. Yes, torsion bars are a good idea. It has a set of mopar performance V8 bars in it. I have a set of six cylinder bars I can try
@@Nicksvintageiron That’s funny, because of watching other people’s Mopar videos is what really got me back on this car. The white Duster is just kinda on the back burner for now. The trans is back together and working good though. The 340 is just tired at this point. She needs rebuilt.
G’day again mate. Well done, I think your car is going awesome,considering the cam size and duel plane intake, I do think with a battery relocation and maybe take a seat out or two and it’s a high 10! As for the M1? Why not? It’s only a set of gaskets.
@@JayGuitars1 Thanks brother! I could try taking seats out but I like keeping the car how I drive it on the street. I’m hoping the M1 gets me there without having to take any more weight out.
Check out engine masters season 3 episode 4. Dual,plane vs single plane. The 430 hp engine made 20 more hp and 10 ft lbs and gained everywhere over 4000 rpm with the single plane. It likely depends on the type/style of single plane but in that instance it helped. Not sure on what single plane Mopar intake is the “one”. Maybe a victor junior may work better than an M1? Only way to know is to try. You’ll also need to do quite a bit of jetting changes to get the tune right when you switch from dual plane to single. And again hard to know exactly how great your air fuel is and where the engine likes it between the two intakes. Good luck.
@@chrisw5837 I love engine masters. I wish all the episodes were still on TH-cam. The only way to know if the single plane will work is to try it. Every combo is different.
Awesome I have a 73 Duster I bought in 2011 and put a $6000 paint job on it and put it in the shop to collect dust and bought a 71 Cuda dragcar in 2011 hoping to get around to the Duster this year we also run a Ramcharger I gave my Son the smallblock out the Cuda going back to RB for 2025 and a 76 Dodge 200 in the Mudbogs so we are allways racing something
Yeah, my name is Calvin.I'm a seventy four Duster, just wondering what size tires do you have on the dear? And I'm afraid cause I'm proud to convert them to a Mo profile. I have 2 35 60 15 on the back 225. 70s on the front 15, but it rubs offended well. Just wondering what you suggest or what hot male can I go on the front? And what I'm going to rid of costs because of mood. Because I moved. Move the Lee Springs in. 😊
@@calvingunn8525 I have 275/60r15s on 15x8 inch wheels, on the rear. On the front I have 26x7.5x15 tires on 15x4 wheels. I can believe your 225/70r15s rub. I think 205/65r15 would fit better for you.
Great video to end the Season! At 2:53 Watch a 360 beat a new corvette by 2 car lengths over and over, it will make your day. I'd bet money on the 0.580 Camshaft getting you 10.9x. You are approx. 40hp up from your J's, there should be another 40 in it when you get closer to Trick Flows 0.600 sweet spot. Would like to see the Cam swap results first and then the single plane next.
So your exhaust change definitely aided in top end and overall power. The explanation as to why your first run was the best can be several things. 1. Track surface was better. 2. Car was cooler and if so, may benefit from a cool can filled with dry ice. 3. Ambient air density was better. A tenth of a second is a blink and can be altered in the slightest of ways. The key metric is consistency and if your car has picked up a at least a consistent 10th with the Trick Flows, I'd say they were a good purchase.
@@cutlets6152 I do think the collector extensions helped. And yes the DA was better the first run. She definitely picked up a good bit from iron heads to the trick flow heads. 11.50/11.60s before to 11.2/11.30s after. With a 11.15 best. I love these heads.
@@Duster_Garage l once had a 68 cobra jet mustang (428) that ran low 11’s. I experimented with collectors ranging from 12 to 18”. Not that it would mean anything for your engine but 14” seemed to be the sweet spot. Your Duster is a Very nice ride btw.
The exhaust brother. Chambered mufflers sound good, but definitely kill some power. Kills 10+hp over a straight through muffler for sure. Check out motortrend "engine masters'" series. They did a great shoot out between chambered, straight through, and turbo muffflers. The single plane might pick you up another 10th. Really depends... Usually, the gains are all above 5000, so if your running close to that engine speed after the gear change, we'll probably pick up a little.
@@broz1969 Yes sir. I did see that engine masters episode. That was my reason for making those collector extensions. There is mixed feelings on the single plane, whether it will help. I do shift at 6500 so the rpms don’t drop back below 5000.
I would say that intake, with the right carb, would gain across the board. It might could use a bigger header tube,if flow was restricted by exhaust. Have you put stroker crank? What is that trans? You was shifting it. Sweet Duster.
Air mite have had alittle to do with it but a .15 to .20 is a nice pickup the exhaust flow alittle better plus a weight deduction probably all had a hand in it....very nice looking car too
@@jeffdavis5704 I would have to measure it but I would say it’s in the neighborhood of 18 inches. I would say the general consensus is the chambered mufflers were killing power.
First off she runs great! Second on my dart if I ran it through the exhaust it was .2 tenths slower. I would space the exhaust at the collector and pick up .2 tenths. I also have 3 inch exhaust but it definitely slowed my car down a good bit!
@ thanks man! My comment about the exhaust and how it slowed me down applied to my dart when it was n/a. That video up saw is with an f1d procharger. It’s running great and I’m happy but there’s more to get out of it. Suspension needs work yet. When I was n/a I had a 400 bb not stroked running a best of 11.42. It averaged 11.6-11.75 on hot days but with the exhaust on it was almost 12s on hot days! N/a just wants to breath! Btw what is your suspension? Cuz you have some nice 60ft times for your car. Or at least I think there pretty good
@@ronn147 That’s a badass Dart brother. Boosted or n/a. My rear suspension is just super stock springs, adjustable pinion snubber and Comp Engineering 3 way shocks. Front is v8 torsion bars and 3 way shocks. No sway bar of course.
@ thanks. I really appreciate it. I’ve been working at it all year to get it dialed in. And your duster is running very well with that combo! I do love ss springs they work really well down into the 10s from what I’ve seen. And you’re really close to getting that 10. I’ve definitely subscribed I love finding channels like yours there isn’t much good mopar channels out there. Keep up the nice content and good luck!
How tight and what stall is your converter? M1 might lose a lot,I'd rather have a porter AG unless you go to the bigger cam then the single will dominate.
@@okoko47 Thank you. And you’re absolutely correct. With a stroker kit and a set of these modern cylinder heads. Near 600 horsepower is a realistic goal on pump gas.
@@Duster_Garage i am not on pump gas. since I only race mine. My 418" 340 with rpm heads, single 850 holley and a 4 speed the car has been 9.78 @ 136 in good air.
Hmm…408 stroker? I know that’s the goal, but if your budget is kinda the point of the video series (and it feels like it is, in the spirit of “old backyard drag builder”), keep in mind that you’re already at that 450-480 mark in hp. It’ll be less expensive to “improve the existing engine” than build a different one. Dyno’ing her might be a necessity. And I’m still a huge proponent of boosting that engine. Hell…you can build that 360 to the hilt. She’s 4-bolt and running head and main studs…you could probably put 8-12psi through her, with a turbo and still have room for a 100hp bottle of “Gap Insurance”. Both of those can be done significantly cheaper than building a stroker. Plus, it ALWAYS leaves you in a position to pull the heads and induction of her and build a 408 stroker with those goodies and that would 100% put that engine well over 800hp off the bottle and 900 at 1/2 track. But that 360 is good for 650-700hp with a 68mm turbo. Just something to think about.
The cam would make the biggest difference. It all depends on where you are shifting at and sending it to because if you are under 7000 that air gap should be your best bet. If your trying to get over 7000, then the single plane maybe starts showing benefits but maybe at the costs of off the line torque
@@chrisbreckenfelder7227 I shift her at 6400 rpm. I don’t really want to push the stock crank and rods much past that. I’m hoping the 4000 stall converter and 4.10 gears will make up for any loss of bottom end torque.
@Duster_Garage is the car nosing over in the shifts or are you pulling straight thru? You are right in the wheel house of the Air Gap and from things I had seen, in that range, there isn't much that touches it till you head north of it.
@@Duster_Garage I think the cam lift will make a significant difference and give you a stronger draw. Heads would then be closer to using their potential output of flow. If anything, with what your doing now, I'd open the air gap up to match the heads. I heard it flows in the 220s but can be opened to flow 290 plus, but I've seen them on dynos handling big hp. Mainly you approach limits and see what is the limiting factor and adjust accordingly to what you are wanting to accomplish.
@@chrisbreckenfelder7227 I do have the air gap gasket matched to the fel pro 1213 intake gasket. I know it’s the best duel plane manifold made. I’ve seen guys run high 10s with it. But I really want to try the M1. It will come back off if it doesn’t help.
Guessing the M1 will require you to up the shifts a few hundred rpm... Will you be able to push the converter a little harder on the line? You'll probably need to do that too to get a good 60ft time but for WOT drag racing passes, it might go a little faster. The real question is how much are you going to like it on the street? The M1 may make the car feel lazy while cruising around town and that might turn you off... you'll have to be the judge.
@@steveschlosser6658 I could push the converter a little more at the line. With the current combo it likes to be footbraked to 1300rpm. When I stab the throttle it flashes hard to a little over 4000rpm. That has produced the best 60’ time. The single plane may change that. I’ll have to experiment with it.
@@terrybeck1581 I would say that’s a minimum. But a smaller cube engine would benefit from a little longer. Every combo is different though. A lot of factors affect that.
Gawd Daaaaayum!!! My man! I predicted 10.999 I was close! Hella impressed with what you've accomplished! I'm trying to get back in the groove net year. Keep up the great work and content!

@@geedubb-q1u Thanks buddy. She does hustle when I push the load pedal to the floor. 💪
Yes you are correct. Sometimes pushing the converter is the way to go, sometimes lightly pushing it and letting it flash works better. You'll have to try both on the same day to see which works better for you. Your car is awesome. Love watching this.

@@BigfootsnMopars Thanks Mark. She really has been making some big steps this year. So far they haven’t said anything about a roll bar, but I only run in test and tune.
Congratulations! Straight through mufflers are usually better flowing than chamber muffler’s. I don’t think you will pick up much if anything with the single plane. MAN I’m surprised the track didn’t bounce you with that ET and no bar. Congrats again!
@@Mike-dw7ec Thanks brother! I think because I only run in the test and tune, they haven’t booted me off yet.
I seriously doubt if you'll pick up much, if any, with the M1. Unless you shifting over 6K I think your times may drop. The Air Gap matches most single planes up to about 6000-6300 from what I've read. I budget built my 414 stroker with Air Gap, Eagle SIR rods, Keith Black hypereutectic pistons, Mopar cast 4" crank. Made 460hp/510 torque. Peaks at only 5400. I purchased the Trick Flows as well. My plan is to switch to .600 lift hydraulic roller, up the compression to 11:5.1 forged pistons, Scat rods, maybe switch to a forged crank. I have a Victor 340 I may use. I've seen the Air Gap support 577hp/557 torque in one build. The most I've seen. That's the kind of power I hope to make. Good luck!
@@ragingbull3406 I think you may be right about the intake swap. The Air gap works really well for the power level I’m at but I gotta give the M1 a shot. I do shift at 6400-6500 rpm.
Good luck with your build. I think the power level you’re looking for is very attainable with those heads.
It is great to see the progress. I just picked up a yellow 72 with a 408 and Edelbrock heads. It's a monster. I was told it did 10.80s. With your Trick flows it would be even better. I'm actually going the opposite direction, trying to make it a little more streetable.

@@maximuswedgie5149 Thanks brother! How is it going with the Coronet?
@ I forgot to comment about the end of the video with the new manifold, I think a lot of of us are anxious to see what that does. I talked to my engine builder, the engine really never made as much power as it should have he said. He said he’s going to try a custom ground cam, and thinner head gaskets. He’s only charging me $1000 to go completely through the engine and clean everything to rebuild it. Just waiting for a chance to drop it off at his house, he is about an hour and a half north of my house. for now I just got the tired other big block in the car, my wife and others think I was crazy going through all that trouble to stuff another motor in there that I had instead of just waiting for the new one to get back. But I get anxiety when my car is apart like that for long period of time lol
@@maximuswedgie5149 I know how you feel. I don’t like having one of my cars torn apart for a long time either.
@@Duster_Garage I wanted to say what’s up, and announce some good news. I just bought a 440 I’m gonna put that in the car now, it’s out of a 12 second dart, he’s gonna refresh the engine first.

I can’t wait to post a new video and see your new videos coming up.
@@maximuswedgie5149 That’s awesome buddy! A 440 is going to be a torque monster. Should be a riot to drive on the street. Can’t wait to see how she runs.
MY GUY!!! 1.51-60ft and 11.15 @119?! Holy Crap!! The guys that have been around for a minute, know the leaps and bounds you’ve made on her. And let me tell you, for us old timers that have made a pass or two, that first run felt different through the video. Any seasoned racer KNEW that pass was going to be a monster. She left the line with her pants on fire and caught full blaze at the 1/4 track mark. You’re going to be really close to getting that sweet thing into the 10’s. Which is something we gotta talk about…you and I had talked a bit about a medium sized turbo for her. The thought, of course, is that with the torque you’re putting down & the trans-brake, you don’t even need a 2-step to launch on the bump. You can just get up on her usual launch RPM….She’ll spool a 68mm turbo up by 200ft and that sweet yellow lady will put her ass to the track and DIG, BABY, DIG.
Possibly pulling those heads and putting titanium valve seats & boost rings in it, and a 200hp of NOS?
Just some ideas…anyhow, CONGRATS ON THE PERSONAL BEST!!!
@@NostraThomas25 Hell yea! She is having the best year of her life. I know you would like to see me boost her but that stock bottom end is about at its limit already. That’s the big reason I want to build a stroker. A forged crank, h beam rods and forged pistons would handle just about anything I can throw at it. Btw, she doesn’t have a trans brake. She just launches that hard flashing the converter from 1300 rpm.
That is so awesome! I’m gonna say because of the air. Humidity finally came to fall levels. Less water grains in the air.

The progress is coming along awesome.
With the couple of variables that you mentioned - do one at a time. Perhaps the camshaft first (even though the intake has to come off) ...
See how the car reacts to the camshaft. With more lift the valves should be open longer. Then give the intake a try.
Best of luck to you 😉
You're right, I really couldn't have asked for more. Yes, one step at a time and she might just see 10s.

Those are some impressive times in a quarter mile.. I think a 3000 Stall converter would help..a set 3.91 Gears. Again, that's a nice 340 duster or dart.
Great video. Keep up the good work until I see you in the next video...👍🙂🙏🏻
@@davidlinck7459 Thanks buddy. She does already have a 4000 stall converter and 4.10 gears. Hopefully the next video will be a road test with the single plane intake manifold. 🤞
Great Job! The exhaust is definitely letting it breathe, you can hear it really coming to life on the big end. You’re already past the point where the M1 will make more power. I like the higher lift cam (along with the M1!) you mentioned, too, but even more so with a set of 4.56 gears. But getting to where you’re at now is damn impressive with an all steel street car.
@@drmopar6122 The cam and the M1 might be the ticket. I don’t see a gear swap because of how far I drive it to the track. Maybe a 4.30
Congratulations! I think the single plane will benefit you. In my experience, the loss in bottom end from single plane intake is only really a thing on stock engines. I just found your channel, so I better get caught up!
I'm hoping it helps, the 4000 stall and 4.10 gears should help the bottom end.
@Duster_Garage Absolutely! I have about a 350ish hp 360 with 4.30s and a stock converter in my Duster. I run an Edelbrock Torker 2 single plane intake and it is definitely not soft on the bottom end. Traction is a big problem for me now. My suspension is same as yours other than I have shit shocks. The Nitto Drag Radials i use are part of my problem too. I think I'll make a video outlining exactly where I am at with my car. I saw you did a year or so ago. My best is 13.30 at 104.
@@Mynextproject_74 that’s cool man. I’ll check it out.
I commented yesterday but for some reason its gone today 🤷...Anyway...Congrats on the new PB!! She was running great! Getting rid of the chambered mufflers helped for sure!

Im pretty sure you were making more than 450 hp that day,unless your car is a lot lighter than i thought lol...My car is 3550 lbs with me in it and i ran 6.97 last week,the wallace race calculator says that it was making 517 hp (at the crank) that day,as far as the Intake goes,in my opinion i think if you go with a bigger cam it will help for sure,especially with the heads you have on it now,not sure that it will help much with your set up now but im definitely no expert lol. Its definitely worth trying it tho,always great to get realtime results with changes,and sometimes things really surprise ya that most say wont work! Keep it up man,the car is impressive as always! 👍
@@RT211Racing TH-cam is screwy with the comments sometimes. Sometimes I don’t even get ones then a month later they show up. Anyway. Thanks, I was pleased with how she ran. I would have liked to hit a 6 second 1/8th though. There’s always next year.
@Duster_Garage You will get it man! If not in the early spring then in the late fall,if the DA woulda been at 0 ft sea level that day you would have probably gotten that 6 second 1/8th! Air makes such a huge difference! My car runs almost 3 tenths difference between the summer and fall lol
Good to see you out one last time before the season ended.

@@mopartony7953 Thanks buddy. She works pretty good. I was thinking about an 8” converter in the future but the 10” in there now does flash to a little over 4k RPMs. And you are right, the shift light (6400rpm) comes on just after the traps. So I don’t think I want to do a gear change. Plus I drive it 100 mile round trip to the track.

Anyways man good video and as always you have 1 nausty duster see ya brother🙃
@@Robertadkins-h9c it is the small thermostat housing flang. And the straight thermostat bypass hose fitting like a magnum. Is yours a spread bore flang too?
And did you have to gasket match the ports? These are kinda small.
@Duster_Garage yea mine is spread bore flange as well. When I ported the heads I did port the intake to match. But if memory serves me right stock eddies and stock m1 was a nice match to each other neither one needing ported to match each other. But I'm not sure about TF heads. I know hunter got the track 1 intake with the tf heads and yea trick flow track 1 intake needed quite a bit of clean up work to match...which i found strange it's there intake and heads you'd figure the ports would be the same size lol
@Duster_Garage as far as the m1 intake pound for pound inch for inch is very hard to beat. They do need cleaned up under the carb hat you'll feel sharp edge under the carb hat where it transitions into runners basically the roof of the intake needs some fine tunning and smoothing from bottom of carb hat to runners other then that my opinion best small Chrysler intake ever made. Especially for something 400hp to 550hp

@@timosracecars Thanks brother. It is a nice cam. And it has done really well for me.
I hear ya, it’s like Mopar doesn’t make anything for the old stuff anymore. Shame.
What are those new mini mufflers? Cars a moving man!
@@CashMopar Thanks brother! 💪 They are Schoenfeld dirt track header mufflers.
Impressive gains by removing the exhaust. I know many years back a racer had a 68 dart with a 440 that ran a 3 inch h-pipe with flow masters. dropped the exhaust and put collector extensions on and it picked up 3 tenths. 10.30 to 10.00 flat. Not at all surprised at all at the gain you got.
Your car 60's really well with a dual plane, The only thing i am unsure of is what your converter flashes at. If your converter is loose enough you might not lose much or if any in your 60 ft and just make more power up top. Certainly there could be maybe another .10th in the combination with the m1 intake but will have to test and see.
With the new short block you are planning on building, Have you considered going forced induction?. I bet for the same price or less then the short block your building you could probably order a procharger kit with your current short block and make significantly more power and still keep it very street friendly. Those trickflow heads will cap out just shy of 600 HP so i believe the bigger short block wont be of much benefit vs a procharged setup. Enjoying the content as you progress with your combination looking forward to more content keep up the good work.
@@Mestoc I’m thinking the same as you about the intake. My converter flashes to about 4000 rpm and my low gear set in the trans makes first gear like it has 4.56 out back. Hopefully enough to cover up any loss of torque.
As far as supercharging this engine. The factory cast crank and stock rods won’t handle it. Especially the rods.
That is a nice jump in MPH, hope next year is even better :) I was planning for 390 my 318 or 408 a 360.. but might just go 360.. that thing runs great.
BTW, kinda surprised how small your cam is with that speed.. although i don't know the duration.. i think i overcammed my 318 .525/.532 on 109.. sounds and runs good though.

What is the weight savings w/collector extensions and shorty bullets versus exhaust turndowns before rearend?
Those collector extensions, bullet mufflers, weight savings, and good air all contributed to those two great runs. The 190cc size of TF heads are ideal for 3.58in stroke and rod ratio of stock 360. 119mph? Wicked!
the exhaust saved me 35 pounds. wicked is what i thought too!
usually you can feel engine pulling harder as it nears Peak torque. and yousaid that in video , lol So the other trick was said that paint the Collector extensions and where the Paint stops after racing is ideal length.what is your Stall flashed too?

As for the M1? Why not? It’s only a set of gaskets.
@@JayGuitars1 Thanks brother! I could try taking seats out but I like keeping the car how I drive it on the street. I’m hoping the M1 gets me there without having to take any more weight out.
Nice video!
@@jameswalls7140 Thanks buddy!
Check out engine masters season 3 episode 4. Dual,plane vs single plane. The 430 hp engine made 20 more hp and 10 ft lbs and gained everywhere over 4000 rpm with the single plane. It likely depends on the type/style of single plane but in that instance it helped. Not sure on what single plane Mopar intake is the “one”. Maybe a victor junior may work better than an M1? Only way to know is to try. You’ll also need to do quite a bit of jetting changes to get the tune right when you switch from dual plane to single. And again hard to know exactly how great your air fuel is and where the engine likes it between the two intakes. Good luck.
@@chrisw5837 I love engine masters. I wish all the episodes were still on TH-cam. The only way to know if the single plane will work is to try it. Every combo is different.
Awesome I have a 73 Duster I bought in 2011 and put a $6000 paint job on it and put it in the shop to collect dust and bought a 71 Cuda dragcar in 2011 hoping to get around to the Duster this year we also run a Ramcharger I gave my Son the smallblock out the Cuda going back to RB for 2025 and a 76 Dodge 200 in the Mudbogs so we are allways racing something
@@johndowney4461 Sweet! That’s a helluva collection. That’s really cool you got your son into the hobby too.
Yeah, my name is Calvin.I'm a seventy four Duster, just wondering what size tires do you have on the dear? And I'm afraid cause I'm proud to convert them to a Mo profile. I have 2 35 60 15 on the back 225. 70s on the front 15, but it rubs offended well.
Just wondering what you suggest or what hot male can I go on the front? And what I'm going to rid of costs because of mood.
Because I moved. Move the Lee Springs in. 😊
@@calvingunn8525 I have 275/60r15s on 15x8 inch wheels, on the rear. On the front I have 26x7.5x15 tires on 15x4 wheels. I can believe your 225/70r15s rub. I think 205/65r15 would fit better for you.
Man, you got that thing moving out how much did you pick up from swapping the 727 to the 904 and what stall converter are you running?
@@duster120 I actually never had a 727 in the car. The converter is a TCI 10”, flashes to around 4200rpm.
Great video to end the Season!
At 2:53 Watch a 360 beat a new corvette by 2 car lengths over and over, it will make your day.
I'd bet money on the 0.580 Camshaft getting you 10.9x. You are approx. 40hp up from your J's, there should be another 40 in it when you get closer to Trick Flows 0.600 sweet spot.
Would like to see the Cam swap results first and then the single plane next.
@@ExMxer3 🤣That’s my buddy Bob in the corvette. I am excited to see what that cam will do for me. And the intake for that matter.
So your exhaust change definitely aided in top end and overall power. The explanation as to why your first run was the best can be several things. 1. Track surface was better. 2. Car was cooler and if so, may benefit from a cool can filled with dry ice. 3. Ambient air density was better. A tenth of a second is a blink and can be altered in the slightest of ways. The key metric is consistency and if your car has picked up a at least a consistent 10th with the Trick Flows, I'd say they were a good purchase.
@@cutlets6152 I do think the collector extensions helped. And yes the DA was better the first run. She definitely picked up a good bit from iron heads to the trick flow heads. 11.50/11.60s before to 11.2/11.30s after. With a 11.15 best. I love these heads.
@@Duster_Garage l once had a 68 cobra jet mustang (428) that ran low 11’s.
I experimented with collectors ranging from 12 to 18”. Not that it would mean anything for your engine but 14” seemed to be the sweet spot.
Your Duster is a Very nice ride btw.
@@cutlets2118 Thank you, and thanks for the info.
The exhaust brother. Chambered mufflers sound good, but definitely kill some power. Kills 10+hp over a straight through muffler for sure. Check out motortrend "engine masters'" series. They did a great shoot out between chambered, straight through, and turbo muffflers. The single plane might pick you up another 10th. Really depends... Usually, the gains are all above 5000, so if your running close to that engine speed after the gear change, we'll probably pick up a little.
@@broz1969 Yes sir. I did see that engine masters episode. That was my reason for making those collector extensions.
There is mixed feelings on the single plane, whether it will help. I do shift at 6500 so the rpms don’t drop back below 5000.
I would say that intake, with the right carb, would gain across the board. It might could use a bigger header tube,if flow was restricted by exhaust.
Have you put stroker crank?
What is that trans? You was shifting it. Sweet Duster.
@@CurtisHarrison-g2t Thanks. The trans is a 904 and I was shifting at 6400 rpm. When I build a stroker motor, I planned on bigger headers.
what converter do you have, might have to change that if you are going up in rpm
@@rogeredson8709 it’s a TCI 10”. I really should get a custom built 8” converter.
Air mite have had alittle to do with it but a .15 to .20 is a nice pickup the exhaust flow alittle better plus a weight deduction probably all had a hand in it....very nice looking car too
@@HorsepowerDr Thanks buddy. I think you’re right. A few factors added up to make the difference.
Was you running slicks or the et streets on your passes ? Thanks
@@Homegrown4406 All those runs were still with my worn out ET street SS tires. Have a great weekend.
Kool 👍 thanks brother you too!
Ive heard that H pipe needs to be 8 to 18 inches from end of collector for more torque and better scavaging effect
@@jeffdavis5704 I would have to measure it but I would say it’s in the neighborhood of 18 inches. I would say the general consensus is the chambered mufflers were killing power.
@Duster_Garage I agree them mufflers was choking you down some.
150 shot 🎉
@@Williamxmr That would get her moving. But I don’t think the stock connecting rods would like it much.
First off she runs great! Second on my dart if I ran it through the exhaust it was .2 tenths slower. I would space the exhaust at the collector and pick up .2 tenths. I also have 3 inch exhaust but it definitely slowed my car down a good bit!
@@ronn147 Holy crap! I just watched your video. Your Dart hauls major ass!
@ thanks man! My comment about the exhaust and how it slowed me down applied to my dart when it was n/a. That video up saw is with an f1d procharger. It’s running great and I’m happy but there’s more to get out of it. Suspension needs work yet. When I was n/a I had a 400 bb not stroked running a best of 11.42. It averaged 11.6-11.75 on hot days but with the exhaust on it was almost 12s on hot days! N/a just wants to breath! Btw what is your suspension? Cuz you have some nice 60ft times for your car. Or at least I think there pretty good
@@ronn147 That’s a badass Dart brother. Boosted or n/a.
My rear suspension is just super stock springs, adjustable pinion snubber and Comp Engineering 3 way shocks.
Front is v8 torsion bars and 3 way shocks. No sway bar of course.
@ thanks. I really appreciate it. I’ve been working at it all year to get it dialed in. And your duster is running very well with that combo! I do love ss springs they work really well down into the 10s from what I’ve seen. And you’re really close to getting that 10. I’ve definitely subscribed I love finding channels like yours there isn’t much good mopar channels out there. Keep up the nice content and good luck!
How tight and what stall is your converter? M1 might lose a lot,I'd rather have a porter AG unless you go to the bigger cam then the single will dominate.
@@karlsracing8422 the converter flashes to a little over 4000 rpm. Hopefully it’s enough.
Whats the deal with the white Duster over there. Is it a 340 also?
@@SCfanIam100 Yes, it has a stock 340 in it. The yellow Duster actually has a 360 in it.
What size tires are you running? Front and Rear??
@@JasonCribbs-r9w fronts are M/T 26x7.5x15.
Rears are 275/60r15 ET streets.
Thanks! Great run!! Merry Christmas
@ No problem bud. Merry Christmas
Dude your car is bad ass you could crack the 10s hopefully with that m-1
@@michaelhurley545 Thanks. That would be sweet.
What were your afr's from one exhaust setup vs the other? Did it lean out any?
Either way a gain is a gain! Congrats
Thank you! Idle mixture i had to tweak a little. Top end was about the same. Bank 1 is around 12.8 Bank 2 is around 13.5, a little lean.
I have used the m1 and in my setup at the time it liked 6800 rpm
@@rontofflemire6165 I can only get about 6500 out of it currently. M1 might move that up.
Good stuff, yeah. Ha, if I didn't KNOW any different, I'd say you're a "Mopar or NO car" kinda guy~:)
@@Kman. You could say that.
nice running small block. I run a small block in my road runner, there is hp to be made with them.
@@okoko47 Thank you. And you’re absolutely correct. With a stroker kit and a set of these modern cylinder heads. Near 600 horsepower is a realistic goal on pump gas.
@@Duster_Garage i am not on pump gas. since I only race mine. My 418" 340 with rpm heads, single 850 holley and a 4 speed the car has been 9.78 @ 136 in good air.
@@okoko47 Dang, that’s gettin’ it.
Hmm…408 stroker? I know that’s the goal, but if your budget is kinda the point of the video series (and it feels like it is, in the spirit of “old backyard drag builder”), keep in mind that you’re already at that 450-480 mark in hp. It’ll be less expensive to “improve the existing engine” than build a different one. Dyno’ing her might be a necessity. And I’m still a huge proponent of boosting that engine. Hell…you can build that 360 to the hilt. She’s 4-bolt and running head and main studs…you could probably put 8-12psi through her, with a turbo and still have room for a 100hp bottle of “Gap Insurance”. Both of those can be done significantly cheaper than building a stroker. Plus, it ALWAYS leaves you in a position to pull the heads and induction of her and build a 408 stroker with those goodies and that would 100% put that engine well over 800hp off the bottle and 900 at 1/2 track. But that 360 is good for 650-700hp with a 68mm turbo. Just something to think about.
What rear gear you running?
@@aarvolaredonjunior1032 I’ve got 4.10s out back.
The cam would make the biggest difference. It all depends on where you are shifting at and sending it to because if you are under 7000 that air gap should be your best bet. If your trying to get over 7000, then the single plane maybe starts showing benefits but maybe at the costs of off the line torque
@@chrisbreckenfelder7227 I shift her at 6400 rpm. I don’t really want to push the stock crank and rods much past that. I’m hoping the 4000 stall converter and 4.10 gears will make up for any loss of bottom end torque.
@Duster_Garage is the car nosing over in the shifts or are you pulling straight thru? You are right in the wheel house of the Air Gap and from things I had seen, in that range, there isn't much that touches it till you head north of it.
@@chrisbreckenfelder7227 I feel like she is pulling hard all the way to the shift point.
@@Duster_Garage I think the cam lift will make a significant difference and give you a stronger draw. Heads would then be closer to using their potential output of flow. If anything, with what your doing now, I'd open the air gap up to match the heads. I heard it flows in the 220s but can be opened to flow 290 plus, but I've seen them on dynos handling big hp. Mainly you approach limits and see what is the limiting factor and adjust accordingly to what you are wanting to accomplish.
@@chrisbreckenfelder7227 I do have the air gap gasket matched to the fel pro 1213 intake gasket. I know it’s the best duel plane manifold made. I’ve seen guys run high 10s with it. But I really want to try the M1. It will come back off if it doesn’t help.
Does this guy have any other social medias or just TH-cam?
@@ryancopas4317 Do you mean me? I’m only on TH-cam for now. Been thinking about making a Facebook page so I can use market place.

Shows how much of a power loss with chambered mufflers
@@ronaldrey8474 Yes, I saw that episode. I think it was like 50hp on a 600 horse engine.
@Duster_Garage yeah & ty for replying.
I heard header extension... Lol
@@ronaldrey8474 no problem
I’m sure those bullet mufflers helped
@@Geezer1320 I’m thinking they did too.
Your exhaust change gave you more bottom end
@@rontofflemire6165 I think it may have helped the whole rpm range.
Get a custom 8" converter built for your car that stalls around 5000 rpm or so. You will be happy. It's going to cost 1100 to 1200$ but worth it.
@@Comet-hn3gm I’ve been wanting a custom built converter for years. I think it’s soon time to pull the trigger on one.
340 ?
@@fredsiegfried1707 360
4.56 would be worth a try
@@Patrick-xd8jv more gear would probably help.
Guessing the M1 will require you to up the shifts a few hundred rpm... Will you be able to push the converter a little harder on the line? You'll probably need to do that too to get a good 60ft time but for WOT drag racing passes, it might go a little faster. The real question is how much are you going to like it on the street? The M1 may make the car feel lazy while cruising around town and that might turn you off... you'll have to be the judge.
@@steveschlosser6658 I could push the converter a little more at the line. With the current combo it likes to be footbraked to 1300rpm. When I stab the throttle it flashes hard to a little over 4000rpm. That has produced the best 60’ time. The single plane may change that. I’ll have to experiment with it.
That car has a high 10 somewhere my opinion
@@RobertMcGowan-n4o maybe, but I would have had to be running at a track altitude of below sea level.
Direct Connection Bible says collector length should be 12".
I ran faster with a 20”
@@terrybeck1581 I would say that’s a minimum. But a smaller cube engine would benefit from a little longer. Every combo is different though. A lot of factors affect that.
