- 331 OR 347 STROKER? // Watching a machine shop hone and prep the block for my SSP ROAD RACE BUILD!
i go to Kannapolis Engine and Adam walks us though exactly why my 331 was burning oil and why their was coolant in the crankcase. Should I go 347 or 331?

I feel like using that special tool on Adam’s right hip quite often on my car when It’s giving me issues 😂
🤣 I should have had him use that tool on my SSP that day.
I learned more about piston rings here than I did in 4 years of Auto Mechanics class in high school. Alot of good info here! great video Gearhead!
Thanks Willie! I learned a lot, it's really cool to be working with Adam.
This was a very fun and educational video. I would definitely let Adam work on one of my cars if I lived closer to his shop. He was not only educating you guys, but he was also keeping you safe. I noticed the sidearm when he was working on the block. Good to have good folks with conceal and carry licenses no doubt.
Hey VV! LOL, yeah I noticed that sidearm too! Heh heh, we were definitely safe.
I chose to build a 331 years ago just because everyone else was doing 347s. I have to say the 331 with the 5.4" connecting rods let's the piston dwell at TDC a little longer and makes awesome power at 14 to 1 compression. Wouldn't do it different if I had the chance.
Not a bad way to go for sure. I'll be letting you guys know which decision I made on the channel soon.
Best engine I have ever built was an Eagle 347. A little bit different in that it had an internally balanced crank with Chevy V6 rod journals. The rotating weight came in 3lbs under a DSS 331 kit. Yes, the wrist pin intersected the oil ring, but it never consumed oil. Only change I would've made would be a domed piston to go over 11:1 compression. It was a screamer, 7200rpm no issue.
Sounds like an awesome engine build. I"m definitely leaning 347.
1st time commenting on ur channel. Shouts out to the Machinist. I like his info and attitude. Machine guys never talk like that. 🍺😁👍
Welcome aboard! Adam is super knowledgeable and wonderful to work with. Thanks man.
Ive had both in my 89 notch.. stay with the 331.. more durable combo.. Mine lasted three years of spraying 350hp worth of N20 through it.. Ran best of 8.82 on a 26" slick..
Nice! I've never been in a car when Nitrious was sprayed, but I"m sure it's fun.
What heads and cams were you using?
@@themechanicred Trick Flow
I am building a gutted, front tube fox hatchback. I plan to use a stock block and poke it to a 331. Also will run nitrous. We’ll see how long it lasts
I think you should stay at 331. You already have alot of parts for it. And it's more then enough for what you want it for. By the way I have a 331 superchargerd and it runs great.
First vote for 331 I think, but it certainly wouldn't be a bad choice. A 331 supercharged must be a lot of fun I'm sure.
Adamn knows his shit!!!! I wish i could find a guy like him in my parts……and he stays strapped at work!! Hell yea!!
He really does!
331 DSS Racing Bullet + AFR 185 = Great engine very durable !!! I like full support for oil rings ! Have this combo in ford maverick its been sweet engine !!
Nice combo, should last a long time.
331 will be more durable. the longer stroke means more piston angle at the bottom of the stroke. Big power is for drag racing IMO where peak matters most. Autocross is about a power band you can control and limit inputs (being able to hold a gear longer and control with the throttle). You'll be happy either way especially with AFR heads.
Great point on the auto cross. I think I'm going to also want to do some road racing as well. Great points, you've given me something to think about buddy.
I like the sound of the smaller displacement of the 331 myself. It give the sound I grew up loving in the old Fox's.
Can't beat that sound!
347....... Love watching the engine work being done. Lots of explaining about what's going on. Great video Matt.
Thanks Jim! 👍. A lot more to come. I also hope to catchup on all your vids soon as well.
That's a good buddy, took a lot of his time to explain and help. my experience is machinist value their time over your understanding.
Glad it helped!
OMG Fords and Chevys living under the same roof, what's the world coming too. Another great informational video.
🤣 Right? LOL. Thanks man.
Im Running a 331 systemax intake 75mm plate i have the 185 AFR its supposedly right about 448 HP, I have Yet To get it on the dino but its been really reliable, 331 AFRs my Vote 👊🇺🇸💪👍🦊🚘🔧🔧🔧🔧
Thanks for letting me know FordTech. I am looking at the SystemMax as my possible intake as well.
I would ask Adam, wear and tear wise, which would he suggest. Either build would have enough hp for the type of racing you are planning. 347 sounds nice and if he figures it wouldn't matter wear and tear wise and the money isn't an issue, go big or go home.
Agree on all points, especially the Go BIG or Go HOME! LOL
My vote is to stay 331/333. Money saved on a new crank can be put towards a nice set of afr 195s or trickflow 11r190 and maybe get ahold of ed at FTI and have him grind a custom cam for you 😏.
You're definitely right about the money savings, and I've always wanted a custom grind, but we'll see on that one.
I have the 302 block from my first car (93gt bought when I was 15) being stroked to 347. Systemax kit. All going into a 83 GLX. Can’t wait to see what power it puts out. 20 year dream coming to reality.
Incredible video
WOW, that GLX is going to move now! Thanks and enjoy your build.
What's the odds that we both have motors at machine shops? Tho my block is a chevy 350 (well 355ci technically now). I don't know if you had the same experience as me, but when I was at the shop talking with the machinist, I kept learning so many new things. Like I totally wanted to hang around him for a day and learn about engine building stuff that I've never thought about. Folks like these guys are just are a blast to talk to. I would go 331ci b/c this motor is going into a road race/autocross car. Piston speed with a stroker is faster so higher rpms it may not be a total fan of which you will be in most of the time for those style of events. It's not always about hp/torque but reliability when staying in those higher rpm bands all the time.
-> I don't know if you had the same experience as me, but when I was at the shop talking with the machinist kept learning so many new things., C'mon Sammy it's me, so yeah I was learning on everything LOL, but yeah that's the cool part. Good call on everything else you mentioned. Adam and I are going to work through those details and of course I'll let you know not only what we decided, but why.
Wish I had gone and checked out the process when Adam was rebuilding my 306! So cool to see behind the curtain at KES 👏👏👏
Adam is the MAN on that stuff for sure.
Hi I have been building motors since 15 ,I am 66 in April ,I have just built 2 347s for friend,67 and 70 mustang fastbacks i would put 302 Twisted wedge motor I built in 95 mustang against either one,the TWs are180s they make bigger ,also p51 from kasse make great power I have 20 Ford motors rt now doing couple cleveland fitting yates head with try y intake GOOD LUCk
Wow, it sounds like you've got a lot of experience that's cool. I did decide to go 347.
Saw that they say 331 easier on bottom end I was singing 289/302 7500 all my life my ranger accidentally hit 8000 have you tube my pro 5.0 Gt 40 p will bring up 13 videos
Very cool to see the rebuild process first hand.
Yeah, I"m hoping to do a couple of more videos over there. Thanks Ponie.
@@GearHead704 looking forward to em!
Now that's a great engine builder. I learned so much. Now if you could be so kind as too how much his services cost .
That's a good question! I don't know yet actually LOL
347 here on my 92 with a trick flow top end kit. On the dyno the car made 340hp to the wheels.
Not bad at all. I've got a TFS top end kit on my vert too and I'm happy with it.
347 love your videos!
Thank you Bob.
I would go with the 347 but this was interesting video!!! But it's yours do want that crazy about the pistons in the bore in the block! Good video Matt
Thanks and that's the way I'm leaning buddy.
Had a 347 now I've got a331 and it turns 7500 rpm s and work s much better doesn't drop off at the other end of the track. Better cam and afr heads did the trick . . AMERICAN CYLINDER VERO BEACH FLORIDA..RON RAINEY ...AND LYNN BEST SHOP IN FLORIDA. SO SAD RON NOT WITH US ANYMORE. SURE MISS THAT FORD MAN ...
Oh sorry to hear that.
For me 331 is the ultimate setup for sb windsor, piston pin height not sitting in the rings. Great stroke vs torque / rod ratio etc. That said 347's haul some serious butt. For all out pwr prob go the 347 and something that expected to have lots more miles 331.
Great point Mark. I think we are going to cover some of the piston pin height issues in a future video as there has been a lot of questions about it.
@@GearHead704 Probably also worth talking about late oem roller blocks and the use of mains girdles. They're a mighty mouse engine. You have a great engine builder. He really knows his craft.
Very knowledgeable. Learned a lot so thankyou for sharing.
Glad it was helpful!
Depending on the cost difference but if the price is minor, I would go for the cubes personally 347
Leaning that way.
@@GearHead704 unless there you’d be a significant differences between the blocks for horsepower/torque on different circonstances, plz enlightened me cause my knowledge is limited....
We'll be covering why I went the way I did on the channel for sure. I'm also learning most of this as well.
@@badasspecv the case can be made the 331 has a better piston ring location for both boost and longevity...but how long do you really need the engine to last? If you take it apart every race season, you can catch a ring going away. If you are building for the street, you may not leave an engine alone for 100,000 miles.
As for power potential, figure out the RPM you want to operate at. Or if you have a head limitation, choose a displacement where that particular head makes the power you need at the RPM you're at (off the dragstrip line, off the corner, down the straightaway, crossing the finish line at redline, etc)
@@albertgaspar627 you realize that there are countless stock engines that have similar if not worse piston ring locations than the 347, my last one went 212,000 miles trouble free when I sold it.
Stick with 331 but use AFR if it's an a car street driven. It will be a very wild ride. Also, check with Adam if he drives a Delorean, he looks familiar.........
AFR is probably how I"m going to go because of the availability issues with TrickFlow right now. I don't think he has a Delorean but I"ll ask. It's a cool car.
I would be curious in hearing Adams thoughts about wrist pins intersecting with the oil ring groove in the 347 as apposed to the 331. That’s a thing that always made me prefer the 331. Unless something has changed and they make 347 pistons that don’t do that.
We've had quite a few questions on this, so I think i'll cover it in an upcoming video with Adam if we can.
The newer pistons are better, but there's still the issue of room. Push the rings closer together, and detonate, and pop went the weasel. If you're boosting, go with the 331 and use its rev-ability. If you want to make power below 6,000 RPM, go with the big bore Dart 363 block, and get a 347 short stroke and less valve shrouding.
I like the low deck Windsor, but it was originally designed for a 221 cid power ability to move an economy car, with the tall deck Windsor to do battle against the Chevy 350. So there's gonna be some limits :)
@@GearHead704 would you happen to know if a regular 331 stroker is just as good as the forged 331 stroker? Or if it's better to by a forged 331 stroker right off the bat?
All depends on what you are going to be doing with it
@@GearHead704 if I wanted to do a carb swap, long tube headers, heads, letter cam, 3.55 ring and Pinon? What would you apply?
I'm intrigued by both Strokers. I've considered the NA 347...but I think I'm going the boost route. I found this video very informative 👍
Glad it was helpful! You'll never beat boost for straight HorsePower numbers.
Im thinking BOTH! 347 and boost if not 363 or 408
347 with AFR heads. Great video!
That's probably what's going to happen!v😁
As far as trick flow, they are having trouble getting heads manufactured so unless you're willing to wait till April I would go a different direction. Definitely go with bigger heads though. 185 or larger especially if you want some kind of boost. God bless
Yeah, I'm seeing the same issue with Trickflow right now.
A customer of mine just ordered a set of Trickflow 11r205's and got them within a week.
Guess what. ITS April
Now you know what way I'm gonna sway on this topic!!!! 347 with afr heads.... That'll get you the HP you want and put a BIG smile on your face!!!!😁😁👍👊
Hah hah, yes I did Joe and I think it's going to be a great way to go LOL
@@GearHead704 im building another 347 and my builder said AFR heads are the best way to go for the flow...
Mine likes them a lot too, although says trickflow is pretty good too. Trickflow is out of stock, so looks like we may go AFR, but we'll see.
@@GearHead704 ill be keeping a lookout on your updates!!😜😜👍👊
MATT! VERY VERY COOL VID ! HAPPY FOR U THAT U ARE WORKING ON THE NEW SSP MOTOR
Thanks Mike, me too. It had been too long since I had some SSP content.!!
Stay 331 you already have the crank and rods. More RPM w/ trickflow 11r 190 heads or the AFR enforcers are a nice reasonable price
Adam usually has the DSS inline/tw pistons on the shelf. That would be a screamer.
I really do want those TrickFlow heads!
I went with the 331. I figured if the OVC crew are using it for their continuation 65 GT 350s, it must mean something.
Either one is a good choice.
347 sounds good just saying brother great view
Can't go wrong, thanks man!
my old 347 combo is still hanging in with head studs, but starting to get some oil consumption issues much like your 331. looking forward to seeing final combo and assembly video
Sorry about your 347. Adam says the oil consumption issues on them have been solved, so we'll be covering why in a future video on the channel too.
331 babyyyyy
Not a bad way to go, although I ended up choosing 347.
I'm working on a 408ci, and remember the Cam looses RPM range with the longer stroke too. I wish I would have known before buying a Cam!
408 is going to be fun! Yeah, we are looking at the right RPM, I may have to change my cam.
Double checking, we have the same cam you mentioned in the video. I need a high stall converter.
The power difference estimate doesn’t seem large enough for me to personally do a 347 if I already had a 331. So I’d stick with the 331.
Makes sense. I think i've decided to go 347 just because I want to do another build in the future.
The 332" on my channel makes 530hp at the crankshaft, I shift it at 8500 rpm, still running great since I built it in 2000. Very durable and powerful combination.
Awesome Bro. I see yall still grinding on the motor. Keep up the good work Bro
Trying over here LOL. Thanks Ant!
347!
Watching the honing process was pretty cool to see.
Hey buddy! Yeah I liked that too, and I"d figured you'd say 347 LOL
@@GearHead704 YEP!!! Go for it! Also, dont cry too hard Saturday. GO DUKE!!!
@@ryang9425 🤣We lost to Clemson because we were getting ready for Saturday instead LOL
@@GearHead704 yep! Back to back losses coming up. Lol Get Tarhole Fox wrapped in the right color blue afterward lol
@@ryang9425 You were saying sir? LOL
Fast car stuff right here
Not 700, but fun in a Fox buddy! 😉
I think 347 but the 331 will probably be better for road racing as well you should reach your power goals with eighter I'm thinking about talking to Adam about me a stroker for my other car it's a 308 right now we definitely need to spend more time around him.
I'm thinking maybe the TRQ might be better with the 347, but really can't go wrong with either one. Adam is a great builder, he actually helped me out a while back and fixed my lower intake manifold.
4.030" with 3.25" stroke is 331.65 cubic inches. In math, we round up at .5 or more, so why do people always call this engine combo 331 instead of a 332? Especially since the 332 was Ford's first FE engine, so it's kind of cool to bring back the label.
Didn't know. I'm not sure why 331 is the popular nomenclature
I own Ugly Kid Racing Engines in N.C, ive been doing the stock block 8.2 deck motors for 20+ years, i think since you are doing a N/A setup 347 is the way to go, and a set of Trickflow 11r205's would really make some good power. Trickflow is always my first choice, Edelbrock is my second.
I really do want Trickflows too. I have a set of small entry level 170cc's on my vert, but I love them.
@@GearHead704the trickflow work, ive got a car called Suicidal 306, it went 5.75@118 after switching to a trickflow 11r190 head, and the motor was worn slam out. The videos are on here under "Sandman91mm" my world record nitrous sbe 302 passes, and the Nitrous stock block record is on there.
@@Uglykidracing8.2 Wow, this quick. I'm not a big drag racer myself, but these Fox's are perfect for it.
347 All the way !!! Trick Flow heads
Definitely want those heads. Trying to find the ones I want in stock right now is proving challenging.
AFR heads for the win, no replacement for displacement!
They are a great choice! I did go with TrickFlow 11R 190cc's though.
347 bro !! Great blog man !!!
Appreciate it buddy!!
347cu in !
That is the way I went.
Damn Adam got skills
💯 percernt!
347 is what I want to see 👀
That is what I chose. Hopefully get it in the car this year.
Slightly more compression but not too much because of the pump gas cold air induction anyway it runs very well
NIce
I don't know if this guy went to college, and judging by his knowledge of measurements, physics, geometry, etc., he very well could have an engineering degree - But I'd say his brain is vastly superior to any recent liberal arts graduate.
Adam is definitely a sharp dude.
Honestly. He may not have... Just years of experience... That's just what ya need to know for engine building
@@strydyrhellzrydyr1345 Exactly,just a gearhead,im not a smart by any stretch but when there is a problem i just dig in,majority of people are scared to do that,about a year ago my washing machine conked out,i knew about washing machines as much as i would know brain surgery,stripped it down found out what was wrong and got it fixed, same with cars, engine building,computer repair etc,just dig in and read and learn and you'll figure it out.
I’d go 331/AFR 185s
Not a bad way to go for sure.
347 will have better torque. It will help with the afr185 heads and make a really fun car. I think you will be very happy either way on cid as long as the afr heads are on it 🤗
The AFR's and the 347 is the most popular suggestion tonight LOL, but good points all around.
Adam knows his stuff would see what he would recommend probably could build either one for autocross ever which one has best low end torque 331 my guess more reliable to
Yes he does, and I'll be working very closely with him on it. Thanks Robert!
Generally speaking, the larger displacement is going to make more low RPM torque, but its also a matter of head port size. Figure out the head you can afford or your class allows, and recognize which displacement will perform best with it at the RPM you want to be spending most of your time at.
I'm sure at 3:47 is fine more cubic inches but I rebuilt my 302 with a 30 overboard and I am very happy with it of course it is modified I put some heads from the 70s on it that I poured it in polished heavily and put bigger valves in I went with those heads so I could have screw screw and studs and rockers I went with stainless steel 1.7 rockers I went with a larger isky cam 24 lb injectors full length and headers a better chips so that I could cut out the 6250 RPM fuel cut outess slightly more compr
Nothing wrong with a 306. I have had one in my vert for almost 3 years now.
I'd say 331 durability, high rev. Faster rev. Less side load on block, pistons, mmeams more passes say 300, 1/8 mile👍🏁🚩💯
Not a bad suggestion. I ended up deciding i'm going to build a 331 for something else and go 347 for my coupe.
adam knows his stuff...
💯 perecent
for boost i'd go 331 all N/A 347 .. We have a 331 for our foxbody
Yeah, I"m going 347 I"m pretty sure brother, thanks for the advice!
347 Stroker the best believe my .
You should check with the local autocross club to see what rpms they run their motors at. I doubt you will need a huge top end hp number. Btw... Great video too.
That's a great suggestion. I better hit up WarHorse Racing as I'll be following his circuit some. I do plan to track it (Road Race) as well.
You can never go wrong with more displacement.
Right! 100%
351 😂😂 but I would go for whichever one makes the most torque. For auto cross torque would probably make the biggest difference. Adam is the man.
LOL, I figured you'd say that Brent! Yours is a beast. I think that 347 is going be pretty torquey! Yeah Adam is the man.
@@GearHead704 oh yeah I agree.
Why the cylinders were all .0015" or larger over standard oversize is a question for whoever machined the block originally, unless it's been apart and subsequently rehoned to death. The second rings should have minimal wear on the bottom of the ring as suggested, the ring in the video is worn out.
The 3.25" stroke crank does offer a bit more stable piston at bottom dead center than the 3.4" stroke, which isn't a deal breaker but ultimately the longer stroke will have a bit more piston noise and potentially some oil consumption due to that rock at bottom dead center. We are discussing .075" difference so it isn't a massive difference.
While modern pistons are very accurate, I always have the pistons in hand before boring in case you need to add a few tenth to satisfy the clearance requirement. Cool build!
The engine was rebuilt at one point, but I don't know what was done to it exactly then. Yes, I'm excited about the build, thanks for watching.
If I could do it again. Aluminum 363 stroker with afr renegade 225 heads and hydro cam. 12.5 compression.
Definitely a great way to go. I was keeping the budget a little smaller this time around.
Go with Trick Flow 11R's regardless of whether or not you go 331/347. Great video.
It's about 50/50 between trickflow and AFR in here. Unfortunately trickflow seems to be out of stock right now.
331 all the way, get some new pistons and roll on !! slower piston speed of 331 will allow a little more rpm with less stress !!
I'll have an update coming soon on what I chose.
Sorry I keep going on but I did a few other things too I put a mean girl on it and a 7-qt pan and also put a girdle underneath the manifold I use the original tube Cobra manifold
No worries, sounds like a fun little setup you got there.
I would go with the 347.
I think that's what I'm going to do.
cocked and locked 1911 - My Man!
😁 he was keeping us safe LOL
347 of curse all day , more power💪🏾🇵🇷
MORE POWAH!!! 😁
You already have the 331! Just add the 185s
That was the plan, but unfortunately I have to buy new pistons so it's got me thinking all kinds of things.
I need to find a guy like this in florida for my build!
Adam is fantastic. Might be worth the trip.
347 all the way
That's what I chose
Currently deciding to go with my mechanics custom 349 for 2700$ girdled and slap it on my trickflow trac heat top end kit 170cc heads but been told ill be restricted powerwise but will have room to grow from.
It will be a lot of fun either way I"m sure. Nice choice.
There's plenty of 347 stuff I would go 331!
I've decided 347 for my build, but I'm going to reuse the 331 for another project.
Depending on total cost. Crank , pistons, cam , possable rods , it may just be worth sticking to a 3.300 /331-9 set up .
Ready depends on the individual budget .
You already know you have to change the pistons. If you going with a 3.400 crank. You'll more them likely need a cam .
If your strarting from scratch or have damage on parts I'd go 347 but Really no need to up grade if not needing new parts
Unless your trying to max put the effort . You're not going to feel the 10 or so hp less .
I think you hit the main point. It's really a budget decision and HP will be fairly close. I'm leaning 347 and I believe it will be more TRQ which I may feel as well.
I like putting the ultra light cali’s crank with Oliver’s ultra light connecting rods with Cp’s pistons or diamond’s and love the AFR HEADS but if you want to save a bit after going all out on the ultra light set up that in my book is number one best of the best Brox and RHS have some descent heads oh and get a isky cam You need a new cam that made for the new build and again hands down isky is number one I feel and then ARP stud the block Jesel again is what I’d do for a bulletproof build
Or you could just go with the eagle they have a full rotating assembly that’s definitely cost effective with throwing some brox or the RHS heads but for sure 347
I totally forgot about Isky. My Dad loved their cams
Go 408!!call it a day!:)
LOL, yeah that would be a lot of fun for sure.
The Exterior Decor Group hood on that blue Mustang reveals it's a second gen, and it's easy to tell the year--1968 was the year the Feds required all cars to have side marker lights, so without them it's a 1967.
I wonder if the head gasket issue was due to how the intake got tightened down? Who built this engine, DSS? seems like the bore work was sloppy.
Appreciate the tip on the old Mustang, I didn't know that!
Go AFR heads with a the 347 stroker if it is in the budget.
Great choices. Going to be posting my decision video on Wednesday.
I’m here Matt. 50th. Good info, this will definitely be helpful when I need to start making my engine decisions. 👍🏼👍🏼
Love the new name! 50th LOL. Yeah I'll definitely let you guys know all the details on here.
Good stuff thanks
Glad you enjoyed it
Not crazy about 347s, trying to push the pistons throw the side of the block.
Apparently there have been some advances, particularly with piston design. I think Adam and I are going to cover it in an upcoming video.
333ci less Piston side load for longevity!
I think we are going to cover this on a future video with Adam.
Cool video
Thanks, I'm glad you liked it.
The 347 will wear pistons and rings much quicker than pretty much any other. Combo....they have a bad rod angle ratio that puts a lot of side loading on pistons etc..also gudgeon pins are way up in ring packs -causes Quick ring wear-- 347 are only good for making torque ....the 331 has a near perfect rod angle ratio , so no extra wear in motor...331 will put rev and out perform the 347 for longer anywayz..go 331 every time...also if U don't want 331 crank send it my way..👍👍😁..
Plan to use the 331 for another project someday
looks like a 65 mustang ......sweet!!!!
Hey Shane! Someone said it was a 67, but either one it's pretty cool.
@@GearHead704 might be those where so close and you could buy the light kit for center grill for the 65s to...tail lights are a tell all as long as the owner left it stock i work on a friends 65 all the time front end looks just like that
@@ShaneHerald Oh cool, yeah I didn't look at the tail lights, but I'll ask Adam next time I see him.
Go big !!
347!!!
💯
I would consider Whats the purpose off the car. What RPM/PowerBand will you need for the Track/ Road course. Will torque be better to get you out of the corners? I'm curious because I'd like to make mine a Time attack car.
That's definitely the kind of things Adam and I will be talking about. I think the 347 for TRQ is going to be the winner there, but we'll see.
Would have liked to see more of the intake.
Stay tuned, we'll be cover it in a future video.
Just depends on if you want to spend the extra money on a crank shaft! I didn’t see him look at the crank if it has wear i would go with 347 if crank is fine nothing wrong with a 331
Great point of course. My crank is ok. I'm thinking of using the 331 components on a different build.
@@GearHead704 that will work also! Great content on the channel
If your sticking with n/a I would go with 347, there's no replacement for displacement specially when your n/a,
Right! Good call.
