Back in the mid 70s I owned a 16 foot ski boat with an Olds 455 to Jacuzzi jet drive. Motor was balanced with a Isky cam. Fuel was always Chevron Custom Supreme (100+ octane) thru a Holly double pumper carb. When you stomped on it, the boat would hit 75 mph at 6000+ rpm. It drank fuel like crazy. Would haul 6 skiers from deep water starts with ease. It was a blast to own and run.
My parents took my sister and I to the Oakland Estuary to the Berkley Jet boat dealer in 1966. They picked out a 16' green and gold metalflake boat with a 350 hp 327 Chevy engine, and we went camping and skiing just about every weekend during the summers. It had a top speed of 62 mph but got there in three seconds..

An old, experienced exhaust specialist told me years ago that a Pontiac V8 & a big block Mopar are the 2 hardest engines to quiet the exhaust sound. (I was there getting mufflers on a Dodge 440 & i must say i had to agree with him.)
Would love to see this build with another point of compression. In the 90s I built a .060” 455 with a solid flat tappet 10:5.1 compression BBC solid lifters and roller rockers and some smog 6x heads that I ported with an 850 Holley on a RPM Air Gap that I ported. It was in my buddies Silver Anniversary w/3.73s a turbo 350 w/380” converter. At 3750lbs it went 11.90s on Horsepower. We put a 26” slick on it and 73N 63F jet in a Cheater plate and the car went 10.33. That was in 1998 or 1999. Factory connecting rods with ARP bolts and the beams polished and weight matched
Love it !!! Those were the good old days when us Pontiac enthusiast's didn't have good parts to work with. All we had was our brains and determination :)
Started of thinking to going back to the quadrajet. Definitely better gas mileage tooling around town, and the back secondaries are like kitchen sinks! Set up right, they're as responsive as any holley or edelbrock .
@@Fhita1962 Qjs are definitely more responsive than the square bore Holleys, or even the spread bores. Qjs have a double booster on the primaries, that no other4bbl has. It equates to supreme throttle response and better fuel mileage compared to brand Xs. (when it is all set up correctly.) Of course, nozzle drip is excited much easier, and can be challenging. But worth the effort on a street machine. As for Edlebrock carbs, they never made (invented) them. Just stuck their name on there.
Well it is going to rev a little quicker because your just running a auto drive plate without the weight of the converter. Any way very Nice .I have built may of these as well. They are a beast.
The Flow masters use the delta flow technology that are welded inside the muffler casing made of thick metal so they are less likely to fail and blow out like a glass pack type of muffler that uses a thin perforated core wrapped with packing . At the speed shop I worked at years ago most of the times the Flow masters made more HP on the cars that we installed those on when we would run them on our chassis dyno and did prior runs with the stock exhaust or a exhaust that had run glass packs or the turbo mufflers and then we would run the car again with the Flow masters and they usually made more power especially once we started jetting for optimal HP and torque along with timing and advance curve settings. We had several turbo mufflers on big blocks that were new that actually split open at the seams and crimps because they were to restrictive and stopped recommending them verses the all welded Flow masters . My boss had a 78 pro street Elcamino all tube chassis car with a certified cage that was making 1,500+ HP to the rear wheels that had a stroked and blown 454 Chevrolet engine and he used the welded Flow masters on it and they took the punishment from that engine no problem. The car could be driven on the street but could knock off 8 second 1/4 miles when driven to the tack and some tuning changes made with the blower pulley. We built a certified tube chassis for a customer who had a 69 Pontiac GTO that was at one time a national record setting drag car that had a 455 using Kaufman heads and custom roller cam with the firing order changed with a aluminum sheet intake and a 5,000 cryoed custom crank that years ago was one of the quickest and fastest all Pontiac powered drag cars here in the good ol USA that was running mid to low 8s at a 160+ mph in the 1/4 mile that was named Bottle fed Goat which I still have a picture of it hanging in my garage to this day . We used to test and tune the car at the Brainered international raceway back then to work the bugs out of the car before the owner started racing it all over the country and setting records with it until he eventually retired from racing and sold the car and I've been trying for years to find it with no luck unfortunately.
Well said, the only problem I had with a set of Flowmasters I ran for years, was the inside divider plates rusted loose and eventually block flow :( @@peteloomis8456

Wow that sounds great! My first race car in high school was a Pontiac Lemans sport. Which I still have in the garage with a 455! I can just imagine what that engine with a set of RAM AIR V heads would be like!
@dcimotorsports1111 ya it's been hard over the years! It's a 1971 Lemans sport with a 455 and a turbo 350 I built in tech school in 87! I've had my car since 84
I had one in the 70's. 389 SD with tri power. I put it in a 1968 LeMans Sport. 400 turbo with Hurst dual gate with 3:90 Limited slip posi differential. I did a 10:70 qtr. mile with it in 1976.
Sounds like Pops was a smart man :) Thanks for following !!! Make sure and check out our bench racing Podcast every Wednesday night from 7PM to 8PM Eastern.
@@dcimotorsports1111, yeah, my dad brought a few add on’s from Super Shops back in the day… I just want to recreate a little 68 or 69 Lemans like he had with a little street engine in it to cruise to car shows… But, when I saw a video of your shop and performance and quality work, I was sold on where I’m going to get an engine from…👍🏾
Had both of those mufflers on my 67 Chevelle at one point. The FM’s had the cool factor at idle no doubt, but were annoyingly loud at “cruise”. DM’s were exactly opposite. I drove more than I idled, so I chose the DM’s.
Agree and same reason why I use Dynomax or Magnaflow. Thanks for following !!! Please subscribe and hit the notification bell for future videos. Come hang out with us on our Bench Racing Podcast every Wednesday night from 7PM to 8PM Eastern.
Great sound either way. Love the lope of the cam... reminds me of my 69 400 RAIII engine that I snatched from a 69 Judge, had rebuilt and then put into my 68 Firebird, in 1976. The car had a 278 gear, but still turned 12.80 @ 123 mph at Fremont/Baylands raceway.
My dream motor in a 70 GTO, with a stickshift, and no balony slicer or stickers. (nice job on this one guys) P.S. The carb looks like an 800 cfm,1977 emissions carb, with the secondary pull-off. (?) Would need some major recalibrating to be worth a snot, which sounds like has been done right. Always wonder why GM put that casting well for the MC solenoid, but left it M/T. Don't believe it provides anymore fuel in the fuel bowl.
This is one of my most common builds and will put just about any car into the 12's on DOT's and 93 octane. That well in the carb can be a benefit when the float bowl is modified properly :)
@@dcimotorsports1111 Yes. No details, just if the MC well can connect to the original fuel well, to provide more capacity. I remember a round plastic filler.Yes or no? Thanks.
@@joequillun7790 Yes as you state remove the plastic cup and there is a slot that runs on the side of it that can be lowered with a cut off wheel. carefully of course :)
Both mufflers sound great but I love the sound of the Dynomax. In order to make a standard 400 hp (1977 - 500577 block), what would you do to make it perform? I'm looking for an upper 12 second street car. It has 3:42 gears, a holley 750, torquer 2 manifold, 1.52 scorpion Rocker Arms, a custom grind cam thats slightly hotter than the Ram Air 3, hooker headers, thought I wasn't to change to ram air exhaust manifolds, a coan torque converter Eventually, I'd let to get a 3 angle valve job Should the heads be ported and polished as well? I was thinking of getting an Edelbrock performer for and getting a perfor m ance kit for rochester carb from Clifs. What do do you think? Any suggestions?
Scott the 557 blocks are pretty weak and the mains will blow out with not much over 400 HP. So you may want to consider an earlier block to build on. I would not use the performer, the performer RPM is a way better intake. Q-Jets are awesome carbs, but will require a killer fuel system for anything over 350 HP. With the correct cam and cylinder head work 12's is achievable. Porting would just be icing on the cake.
Watch my video I just posted of the 1st to 2nd test hit in a 68 Firebird we just finished up. Hits the rev limiter immediately in 1st and 2nd gear. Its all in the cylinder heads.
@@dcimotorsports1111 I saw the video of one you did last year and it's reve was unbelievable. People say how fast mine revs but that thing was like a two stroke w really small sprockets

I wonder if you could shoot spray paint into the carb so when you pull the intake off you can see the paint patterns in the port areas. Maybe on a flow bench. Let e know if you do this

quadrajets work amazing when you rework them i used to get a lot from mondello performance they had a throttle shaft bushing kit that kept the carb from pulling air and howling that with a few other small improvements and it was an awesome carb
Yes they are !!! Not many put 2 and 2 together with the name of my company, but the DCI in my company stands for Don's Carburetor INC. I changed the name of my company in 1995 when I bought my partner out. So I have a very good understanding of the Rochester Quadrajet and actually wrote a hop up manual on them.

@@dcimotorsports1111 I rescued quite a few of them from dumpsters do you guys have an online store that sells stuff for them ? Im building a mopar 383 i plan on keeping a few quadrajets on the side for different situations.
@@dcimotorsports1111And what's the name of it? I don't need one, but I'd like another one, for some reason I enjoy the QuadraJet manuals, have every GM one available from the early 70's to the early 90's, I have a Gherraty one, he focused on RV economy and power, it's good reading. The people that criticize or trash on QuadraJet's either don't understand them or have never experienced a great running one
Sounds great ! For a 5200 rpm mill ... Nothing but love ! I'll take the old school 375 or 425 wildcat over anything else all the way , when it comes BOP . Sweat motor for sure , especially for a truck .
Really, the 2 different mufflers each sound great, I usually like Dynomax, but this combo sounds great with Flowmasters. Even open exhaust is still very nice and not too radical sounding
@@daryllect6659 why is your wrong opinionated information even relevant? I’m guessing you’re a damn Chevy only fan by your comment, so whatever you’re a fan of makes monster power on every engine they’ve ever manufactured?

They always rev fast without any torque converter or other drive train hook up to them. P.S. Turn your phone sideways, and the image will fill the screen.

I took one of those and bored it .108, put AMC 390 12:1 piston which had the perfect piston pin position to use Chevy .400 over length rods which had a smaller rod journal than the 455. Offset ground the crank by .030 stroking the engine to .060. Came out to I think 502 ci with 14:1 compression with the small chamber heads. It was in the 1980s when I did it.

Pontiac was the main reason for the Super Stock Class back in 1962 . When I was a young fella , I used Pontiac 455 blocks and Isky cam and 400 heads huge bang for your buck in the old days .
Nice 👍 my friend back in highschool stuck a 455 in a 80's Buick regal everything stock until he was board and wanted more power but to blow the engine he ran a can of Eather into the back 4-barrow it already would smoke the tires into drive but before it would grab he hit the Either 😂 needles to say he only got to do that a few times before the engine went out that was a lot of fun but the motor All rebuilt was really nice he even out Run our township cops One night they were going to pull him over anyway so he stopped right in front of them about 2am in the morning and he gave that car Hell i sat on the Town bench and watched the whole thing 😂they never caught him but knew who he was and lived 😮 LoL

Was the Flowmaster a chambered muffler? You can get a DynoMax in a chambered design too. DynoMax (Walker) out flows Flowmaster, in all comparable cases. I think they sound better too.
Sounds just like the 400 in my TA my 400 really turns on the rpm ! Been told if I switched to 455 it wouldn’t turn nearly as hard as the 400 with the same cam and parts
400's are fun and have a little broader power band than the 455. I love the 455 for its TQ though. Thanks for following !!! Check out our Podcast tonight and every Wednesday night from 7PM to 8PM Eastern.
No they are a flat top with 2 valve reliefs. The #64 heads have bigger chambers factory rated them at 87CC, but most measure around 93 CC's. Another contributing factor is the pistons are usually around .022" to .028" in the hole which reduces compression as well. So in reality off the production line engines that were rated at say 10.5 to 1 were actually closer to 9.5 to 1. That's why all your NHRA Stock and Super Stockers blueprint their engines to factory ratings.
Love your videos. Im building a 428 with ported 96 heads. Was wondering your opinon of a nice street strip cam? Its going in a 69 gto with 355 gears and 2800 stall. I was going with a hyd. Roller. Thanks have a nice day

Wow that sounds great! My first race car in high school was a Pontiac Lemans sport. Which I still have in the garage with a 455! I can just imagine what that engine with a set of RAM AIR V heads would be like!
1972.... Lemans Sport... Nice looking car alright
That's to cool, wish I still had my high school car. It was a 68 Firebird with a Pontiac 350 I built and ran 13.60's on M50 bias ply tires.
@dcimotorsports1111 ya it's been hard over the years! It's a 1971 Lemans sport with a 455 and a turbo 350 I built in tech school in 87! I've had my car since 84
Back in the 80's my brother had a 1950 Ford pickup & he had a 455 in it. Bad ass old truck.
NICE!!!!
Flowmaster s for me. Their single chamber ones (American Thunder series) sound just right. Cool old Pontiac!
Thanks for the KUDOS
Pontiac fan since the 60s 389 with six pack
Thanks for following :) Love those Trips and the sound they make 🙂
I had one in the 70's. 389 SD with tri power. I put it in a 1968 LeMans Sport. 400 turbo with Hurst dual gate with 3:90 Limited slip posi differential. I did a 10:70 qtr. mile with it in 1976.
Man, this right here proved what my dad was telling me about this engines potential he had in his 1969 Pontiac Lemans…👍🏾

@@dcimotorsports1111, yeah, my dad brought a few add on’s from Super Shops back in the day… I just want to recreate a little 68 or 69 Lemans like he had with a little street engine in it to cruise to car shows… But, when I saw a video of your shop and performance and quality work, I was sold on where I’m going to get an engine from…👍🏾
Thank U Sir !!! @@southtexashustler
Had both of those mufflers on my 67 Chevelle at one point. The FM’s had the cool factor at idle no doubt, but were annoyingly loud at “cruise”. DM’s were exactly opposite. I drove more than I idled, so I chose the DM’s.
Agree and same reason why I use Dynomax or Magnaflow. Thanks for following !!! Please subscribe and hit the notification bell for future videos. Come hang out with us on our Bench Racing Podcast every Wednesday night from 7PM to 8PM Eastern.
My self I'm a magnaflow person that I put on my 69 gp sj 428 and added the TA, tips but I do like the sound of the good old cherry bombs
I had a quadrajet done by a guy in California for my 396
Worked out was flowing 950 cfm & that motor took it all....
Beast 🤘👿🤘
I love the Q Jets, just wish they had bigger fuel bowls.
I like the Dyno Max Mufflers and used to run those on my truck as well for 12 yrs. Running Flowtech now to match my headers.
Its funny how we all used to like Flowmasters back in the day :) I'm with you I like the more mellow tone.
Great sound either way. Love the lope of the cam... reminds me of my 69 400 RAIII engine that I snatched from a 69 Judge, had rebuilt and then put into my 68 Firebird, in 1976. The car had a 278 gear, but still turned 12.80 @ 123 mph at Fremont/Baylands raceway.
@hopebrowning6300 Buick, Olds and Pontiac's torque were the reasons why Chevrolet's Mkt. Dept lied about their hp to sell more cars.
My dream motor in a 70 GTO, with a stickshift, and no balony slicer or stickers. (nice job on this one guys)
P.S. The carb looks like an 800 cfm,1977 emissions carb, with the secondary pull-off. (?) Would need some major recalibrating to be worth a snot, which sounds like has been done right. Always wonder why GM put that casting well for the MC solenoid, but left it M/T. Don't believe it provides anymore fuel in the fuel bowl.
This is one of my most common builds and will put just about any car into the 12's on DOT's and 93 octane. That well in the carb can be a benefit when the float bowl is modified properly :)
@@dcimotorsports1111 Really? Do tell.
@@joequillun7790 About the fuel bowl mod ???
@@dcimotorsports1111 Yes. No details, just if the MC well can connect to the original fuel well, to provide more capacity. I remember a round plastic filler.Yes or no?
Thanks.
@@joequillun7790 Yes as you state remove the plastic cup and there is a slot that runs on the side of it that can be lowered with a cut off wheel. carefully of course :)
Both mufflers sound great but I love the sound of the Dynomax. In order to make a standard 400 hp (1977 - 500577 block), what would you do to make it perform? I'm looking for an upper 12 second street car. It has 3:42 gears, a holley 750, torquer 2 manifold, 1.52 scorpion Rocker Arms, a custom grind cam thats slightly hotter than the Ram Air 3, hooker headers, thought I wasn't to change to ram air exhaust manifolds, a coan torque converter
Eventually, I'd let to get a 3 angle valve job
Should the heads be ported and polished as well? I was thinking of getting an Edelbrock performer for and getting a perfor m ance kit for rochester carb from Clifs. What do do you think? Any suggestions?
Scott the 557 blocks are pretty weak and the mains will blow out with not much over 400 HP. So you may want to consider an earlier block to build on. I would not use the performer, the performer RPM is a way better intake. Q-Jets are awesome carbs, but will require a killer fuel system for anything over 350 HP. With the correct cam and cylinder head work 12's is achievable. Porting would just be icing on the cake.
It has a flexplate and no torque converter, or flywheel. Of course it will rev quick.
Mine does it…. In the car. 😊
Watch my video I just posted of the 1st to 2nd test hit in a 68 Firebird we just finished up. Hits the rev limiter immediately in 1st and 2nd gear. Its all in the cylinder heads.
right...lol
@@dcimotorsports1111 I saw the video of one you did last year and it's reve was unbelievable. People say how fast mine revs but that thing was like a two stroke w really small sprockets
HA HA Thanks@@oldschooltwist18
I've always had a love for the Dynomax. I had some on my 86 Mustang years ago.
Ha Ha Pontiac's are TQ monsters :)
Nothing as crisp as a new or pro built Quadra jet!

I always run Cherry Bombs on all my old Pontiacs,GTO & 2+2, Love that sound!
I had a 68 Firebird I ran Cherry bombs on, but it pissed my neighbors off to much so I switched back to a Hush Thrush turbo muffler.
Pontiacs sound glorious with 60 inch X 3 inch round straight pipes.

Really nice engine build, I like the sound of the Dyno Max's. PRW just came out with a new Quadrajet carb.

I wonder if you could shoot spray paint into the carb so when you pull the intake off you can see the paint patterns in the port areas. Maybe on a flow bench. Let e know if you do this
Good idea, we have done it before with Dykem not paint. Its basically a dye and does show where the air goes. I hate doing it though because it makes a mess out of my flow bench :) Thanks for for following !!! Come hang out with us every Wednesday night on our Bench Racing Podcast from 7PM to 8PM Eastern.
I wanted to hear the Q-jet secondaries open up
It revs to fast and if we crack those open its to 7000 RPM which is way out of this engines safe zone LOL.
flow master
Sounds nice indeed . There is always tuning on the engine after it goes on the street
Sounds great Don.
Nice job.👍👍
Thank U Sir !!! :)
We had one in a 20ft open bow boat and a Berkley jet drive in the early 70's was a beast of a motor.
Nice !!! I would love to build a jet boat with one of my RA5 engines

I like Dynomax mufflers best. I've grown tired of flowmaster. Sounds mean all ways, but love the dynomax sound. Great street engine.
Agree 100%
Yep that’s I remembered about them old Pontiacs. Distributor in the rear up against the firewall. Made it a little difficult to tune up.
It depends on the car they are in. Its not terrible for most of them. Its a whole lot easier if they have electronic ignition too :) Thanks for following !!!
The buick GS 455 cars were nice, guy down the street when I was a teenager had a skylark that he yanked the 350 out of and put the 455 in. He took me on a couple of wild rides and I was hooked for life
Flowmasters.....that's what I have on my Olds 455. Love the sound !!
Everyone likes that sound :) Thanks for following !!! Check out our Podcast every Wednesday night from 7PM to 8PM Eastern.
Nice to see the Pontiacs still being appreciated. Much better engines overall than 1st generation chevy small blocks.
I agree 100 percent, but there are lots that dont agree :)
Nice setup, I may setup my next 455 like that
This is a nice combo and runs really well. Keep in mind the cylinder heads have a big role in an engines performance.
I had a 455 Pontiac engine in a 69 Catalina it was awesome
Nothing like the big TQ of a Pontiac 455 :)

Good video! The Dynomaxs have that classic pop. I've had Purple Hornies and Cherry Bomb glasspacks on a few vehicles I've owned, but I've always been more of a chambered muffler Flowmaster guy 👍
Thank You for the KUDOS !!! I like the deep tone of a good turbo muffler.

My Dad got me hooked when I was a kid. He always had some kind of a fast Poncho while I was growing up. I have fond memories of him rowing through the gears in his 67 GTO, 63 Catalina with a 421, 68 Firebird, ^9 Firebird you get the idea lol.

What kind of choke is on that carb? Looks like a hot air carb but i dont see it connected to the intake.
This is a later model carb with an integral choke and choke housing. These were either heat actuated or electric. We put a electric choke stat on this one.
It'll almost idle smooth once the mass of the torque converter is added.
Its does effect it some but not as much as you might think. Thanks for following !!! Please subscribe to my channel and don't forget to hit the notification bell for any new videos I post.

Does that engine even turn a full revolution before it starts? Sweet !
Gotta love a perfectly tuned engine :)
quadrajets work amazing when you rework them i used to get a lot from mondello performance they had a throttle shaft bushing kit that kept the carb from pulling air and howling that with a few other small improvements and it was an awesome carb
Yes they are !!! Not many put 2 and 2 together with the name of my company, but the DCI in my company stands for Don's Carburetor INC. I changed the name of my company in 1995 when I bought my partner out. So I have a very good understanding of the Rochester Quadrajet and actually wrote a hop up manual on them. I still have the master copy somewhere around here :)
@@dcimotorsports1111 I rescued quite a few of them from dumpsters do you guys have an online store that sells stuff for them ? Im building a mopar 383 i plan on keeping a few quadrajets on the side for different situations.
@@dcimotorsports1111And what's the name of it? I don't need one, but I'd like another one, for some reason I enjoy the QuadraJet manuals, have every GM one available from the early 70's to the early 90's, I have a Gherraty one, he focused on RV economy and power, it's good reading. The people that criticize or trash on QuadraJet's either don't understand them or have never experienced a great running one
I will dig out my master and post a short on it and reprint some for sale. Stay Tuned :) @@kalybnielsen4183
The 750 quadrajet was one of my favorites, albeit hard to come by. I'll take the dyno-max muffs any day, since I do more than idle.
Sounds great ! For a 5200 rpm mill ... Nothing but love ! I'll take the old school 375 or 425 wildcat over anything else all the way , when it comes BOP . Sweat motor for sure , especially for a truck .
BOP all make big TQ 🤪
Really, the 2 different mufflers each sound great, I usually like Dynomax, but this combo sounds great with Flowmasters. Even open exhaust is still very nice and not too radical sounding
Yeah, because with a low RPM, boat-anchor Pontiac, it's all about the sound, not about the non-existent horsepower.
@@daryllect6659 why is your wrong opinionated information even relevant? I’m guessing you’re a damn Chevy only fan by your comment, so whatever you’re a fan of makes monster power on every engine they’ve ever manufactured?
@@DMcElfresh101I'm a Magnaflow fan myself, I think 90% of the people where I live run Flowmasters and drive like they're in NASCAR. As for his low revving boat anchor response, he must have sore feelings when a Pontiac of whatever type blew the doors off of whatever highly tuned machine he was running
@@kalybnielsen4183 definitely not against Magnaflow, used them several times with no regrets! Yes, some people are so biased on “their” brand it’s crazy. I mean nobody was doing great things in late 70’s/ early 80’s far as amazing engine output.
I love open headers ❤

The sound of a good Q.J...when you get in it just sounds like it is going to suck the hood in it
Ya Buddy I used to flip the lid over on my 68 Firebird before I had an open element air cleaner just so I could hear it suck LOL.
They always rev fast without any torque converter or other drive train hook up to them.
P.S. Turn your phone sideways, and the image will fill the screen.
I hear that all the time. Watch this video I did with one in the car th-cam.com/video/4G5OKob-VAU/w-d-xo.html
It hits the rev limiter every time it revs so fast :)
With a stroke of nearly 4 and a quarter inch, you would think this powerplant would be less cooperative when it came to higher rpms! This is one strong Pontiac!!!

Dynomax, open headers sounds good to
😂😂 "Closed Caption on" motor starts, motor idles - music, motor revs - music. 😂😂😂
the only thing that bugs me is the instant start up. good tune but, I like to crank a short bit first to build oil pressure, then fire up
Thank U SIR, for the KUDOS !!! We have been doing this so long now that we get to see engines we built for refreshes and almost all of them we could re use the bearings. Obviously we don't, but the point is they show no bearing wear hardly at all after even 90,000 miles which pretty amazing :)

I took one of those and bored it .108, put AMC 390 12:1 piston which had the perfect piston pin position to use Chevy .400 over length rods which had a smaller rod journal than the 455. Offset ground the crank by .030 stroking the engine to .060. Came out to I think 502 ci with 14:1 compression with the small chamber heads. It was in the 1980s when I did it.
Cool, I like cross breading to get something unique :)

Love the Dynomax mufflers and Magnaflows. I used to like the Flowmasters but not so much anymore.
That's all I'd ever have on my cars is quad jet carbs 71 monte 77 and 84ss they are the best for the buck, and for use in a daily driver as well
It seems people either love them or hate them. I personally love them and use them whenever possible. The only issue with a Q Jet is their fuel bowl size. You have to have a killer fuel pump and big enough supply line.
I like the Dynomax sound

Pontiac was the main reason for the Super Stock Class back in 1962 . When I was a young fella , I used Pontiac 455 blocks and Isky cam and 400 heads huge bang for your buck in the old days .
Nice 👍 my friend back in highschool stuck a 455 in a 80's Buick regal everything stock until he was board and wanted more power but to blow the engine he ran a can of Eather into the back 4-barrow it already would smoke the tires into drive but before it would grab he hit the Either 😂 needles to say he only got to do that a few times before the engine went out that was a lot of fun but the motor All rebuilt was really nice he even out Run our township cops One night they were going to pull him over anyway so he stopped right in front of them about 2am in the morning and he gave that car Hell i sat on the Town bench and watched the whole thing 😂they never caught him but knew who he was and lived 😮 LoL

Was the Flowmaster a chambered muffler? You can get a DynoMax in a chambered design too. DynoMax (Walker) out flows Flowmaster, in all comparable cases. I think they sound better too.
Yes the Flowmasters are chambered, but the Dynomax are not. Thanks for following !!! Check out our Podcast every Wednesday from 7PM to 8PM Eastern.
Second mufflers had more of the crackling sound. I like it 👌.
Throttle response is going to be phenomenal when nothing is bolted to the crank
Course nothing sounds better than open headers lol
Sounds just like the 400 in my TA my 400 really turns on the rpm ! Been told if I switched to 455 it wouldn’t turn nearly as hard as the 400 with the same cam and parts
400's are fun and have a little broader power band than the 455. I love the 455 for its TQ though. Thanks for following !!! Check out our Podcast tonight and every Wednesday night from 7PM to 8PM Eastern.
Are you running dish pistons in it to get that compression ratio
No they are a flat top with 2 valve reliefs. The #64 heads have bigger chambers factory rated them at 87CC, but most measure around 93 CC's. Another contributing factor is the pistons are usually around .022" to .028" in the hole which reduces compression as well. So in reality off the production line engines that were rated at say 10.5 to 1 were actually closer to 9.5 to 1. That's why all your NHRA Stock and Super Stockers blueprint their engines to factory ratings.
I'm a die hard Flowmaster guy,awesome mufflers
Love your videos. Im building a 428 with ported 96 heads. Was wondering your opinon of a nice street strip cam? Its going in a 69 gto with 355 gears and 2800 stall. I was going with a hyd. Roller. Thanks have a nice day
