You could not have gone wrong with either motor because your machinist is top notch. Attention to details is where it is at. That will be a very nice mill. Congrats
Can’t wait to see what you end up doing with the engine build. My 347 was already in my car and I feel like it’s under powered because of the small trick flow heads on it. It’s making 340hp to the wheels but I know it can make more with larger heads and better intake.
I'm going to try and get the biggest intake, heads, cam combo I can that will still be streetable, and will let you guys know what it makes. I'm hoping for 380, but we'll see.
Yeah this guy knows his stuff I didn’t know there was that much the balancing a crank looks like this is very time intensive intentions and ran really smooth👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
Horespower is so easy to buy these days, my faith in stock blocks is at an all time low. I would have a hard time building one. Now the 351 blocks are a bit stronger, and go 408 easily. Either an aftermarket 8.2 block or a 351 for me. I wish you well on this project and hope you meet or exceed your goals.
Thanks Paul! Yeah the 351 will definitely hold a lot more power. Since I"m going NA only we should be good to go with this 347. I'll build a 408 one day.
the benefit to a stroker low deck Windsor is exhaust clearance. gotta get the hot air out, and if you want to use a long runner or Tri Y header, the shorter deck height might help you clear a steering column etc.
I went with the 331 but my compression is 12.9.1. I have a 302 crateno miles. But it's extra engine I'm thinking of a 347 less compression but read for at least. The 331 is built from my original 289
Cool vid!!! I’m in Albemarle and found prestige motor sport in Kannapolis. They did a lot on my 289. I haven’t heard of these guys but I want to learn about them too!! They seem very nice. Take Care
I have a 68 Mustang, 289 with T-5 tranny. I want to rebuild, but I'm torn between a 331 or 347. I'll probably just end up buying a 351W crate engine...
Did the machinist match the lightest connecting rod to the heaviest piston to get a uniform weight, or did he just machine each part down to the lightest uniform weight he could get?
@@GearHead704 it would be interesting (ok, to me at least :) ) because at one time people wanted the lightest possible reciprocating assembly (knife-edged or pendulum cut counterweights on the crank, etc) so the engine could rev to its powerband quickly (a light flywheel can do the same, but flywheels store energy so too light causes issues in some street applications). not a big deal in a circle track engine spending time in the power band, and the question is how light can you be as oil gets sprayed in the crankcase (esp. with oil squirters cooling the pistons in modern engine designs) and gets slung off the crank without windage trays and crank scrapers. but for a street engine that's spending time across much of the rpm range, it could be something that makes one engine feel more responsive than another running the same cam-heads-intake.
I was leaning towards the 347. This guy really knows his stuff. So much that I was getting dizzy with all of the knowledge. LOL Then Foxresto Matt showed up and Della. Ibuprofen please. LOL. Great video though buddy.
should of just got a 351 Cleveland and hooked that up ....they dont need much to run 500 horse...but man thats going to be of hell of a engine man ....wow....
Yeah those are great engines too and can hold more power long term if you want to upgrade later for sure. I didn't want to deal with the stock hood clearance issues though.
Too me this stuff is very exciting. Very glad you did. Actually I would love to see brief clips of the cleaning and ring filing to see it done by an expert. Sorry, but I love that stuff.
Sure hope your ATI dampener is close to his. Unless it was molested by the previous machinist, there was no reason to balance the crank with his "spec" dampener because you already have a quality part, and there is not much area to correct on it, leaving any correction to be done back within the crankshaft. It is possible he will need to add weight back to where he removed on the counterweight. If the imbalance difference between the 2 dampeners is significant it will affect the balance on the back of the crankshaft as well. The manual flywheel makes sense to spin up after the fact since there is 360 degrees of area he can correct on it. I love how his setup is entirely managed by a computer, especially how you enter all the rod weights at once. We're still in the stone ages, weighing all the big ends then matching to the lightest, then all the small ends etc and using good old fashioned balance cards, a pen, and a calculator. 🤣 Good video!
I've decided if it does balance out right with my balancer to buy a different one and use the ATI on a different project. I like the crank being balanced correctly personally because then I can just switch flywheels or balancers as needed. Thanks, I"m glad you enjoyed the video.
It's a good question. For me it's mainly because I want to maintain my stock hood and using drop motor mounts cause all kinds of problems. Also, I already had a block for the 347, where as the 351 would've needed a different block.
Oh damn...I wanted to see Adam grind some rings....NOT...Seriously though, very interesting to see how much time can go into building an engine correctly.
Best to call him and see. Assuming that it's for off road use I really doubt there would be a problem with it, but I don't want to speak for him on it.
@@GearHead704 In all seriousness I was impressed. That looks like a top notch machine shop and the man running it obviously knows what he is doing and how to run it. You are going to have a really nice set up,im happy for you..🔥💪🇺🇲
LOL, I just read your other comment and thought well he isn't going to like the decision I made hah hah. Thanks for checking out the videos anyway man.

Very true! I'm excited about it. Thanks Rob.
Yessss 347 more c.I.! Great video brother!!
You know it Boosted! Thanks man, I appreciate ya.
Love the call on the 347. The machine shop footage is great. Love the info Adam shares.
Thanks, I found that stuff very informative. More to come! Appreciate you watching.
Wow that was very interesting and informative! Can’t wait to see the assembly.
Agreed and that's coming soon! Thanks buddy.
It's been awesome to watch you grow on your channel & so happy to see you having "top notch" quality build.
I appreciate you sticking with me for all this time. I think once this build is done it's going to be very nice and very well documented.

Very cool to see this process
Thanks Jeremy, this was all new to me.
Is there a follow-up video with a dyno run, first start-up, test drive, or anything letting us know how this project turned out?
There will be, but right now it's not even in the car LOL. Slow going sadly 😩

Appreciate it Paul! Now I gotta get busy getting a car ready for it LOL
@@GearHead704 💯🏁
347 dont last long on a OEM block unless u build it watered down . 331 all the way . Ive had a few of both 331 and 347
It'll be interesting to see how long mine lasts (347) if I ever get it in the car that is.
Great video Matt
Thanks DV! Appreciate you watching me in your new theatre space.
Very knowledgeable on engine building. He seems he's very focused on accuracy. Your engine should be top notch.
Fore sure, I feel very comfortable on it being a solid build.
Nice choice. Looking forward to the build.
Thanks, I've never heard of a 347, so I'm excited about it.

Love the 289! Enjoy it.
Can't wait to do business with Kannapolis engine service
I'm very happy with them.
Great choice on the 347! Looking forward to seeing it run!
Thanks Charlie, me too👍
My 347 with dart heads rev 6800 .my 331 with afr heads205s revz 7500 331 in a 2900 lb Maverick
Both sound like fun
Engine building is interesting wondered how balancing was done does make a difference .
Hey Robert! It's been great to get to see all this stuff happen. I know this engine is going to be solid.
My personal 358 8.200 deck Ford is Molnar 3.400 crank with there 5.400 con rod along with Mahle 1mm 1mm 2mm oil ring combo on Race Tech pitons.
Sounds like a nice setup.
Great video your engine should make great power I'm considering a 347 for one of my foxbodys it's a ltd2 foxbody sleeper project
Thanks, and I think a 347 would be awesome for that.
Hmmm... very interesting you chose the 347 over the 331. So is it a daily or track car?
Subbed!
Track car! Thanks for the sub.
@@GearHead704 Right now, I'm running a hot 302 in my 2000 ford ranger, dailydriver/travle truck with ac. Building a blown 331 next year for it

glad to see you went with the 347 stroke is torque which is faster ets if you can hook
I'm really excited about it.

Hah hah, yeah so my knowledge with those guys! I had to film it and watch to get everything LOL
347 is going to be fun! Great video, Matt!
Thanks Tom, I think so too
Nice inside look of an engine build. I'm curious in the price difference if a 347 build and Vortech boosting the 302
Probably similar as the heads, cam, and intake can add some expense.
Great video, I don’t know how I missed it earlier.
No worries and thanks as always buddy
Matt what did he say , cant keep up ? Sooo cool on the rebuild good luck , i want to👍👍👍👍👍👍👍
see u driving the SSP soon
I hope I"ll be driving it soon Mike, but yeah I'm excited. Was there a part where you couldn't hear him?
Awesome info Bro keep Grinding 💪 Stang Life 🐎
Always! thanks Ant.
What’s the compression ratio on the pistons? And what will it be after all said an done?
11.5 or 12 to 1 is what we are thinking
should of just got a 351 Cleveland and hooked that up ....they dont need much to run 500 horse...but man thats going to be of hell of a engine man ....wow....

I'm no motor head,but why not a 351w,instead of stroker 347......351 is more cubes

You got it right Shifty! 349! Thanks, I"m glad you enjoyed it.
Good call on the 347, there's no replacement for displacement specially when your n/a
Ah I didn't say it first lol
For sure! Should be a fun screamer.
Oh damn...I wanted to see Adam grind some rings....NOT...Seriously though, very interesting to see how much time can go into building an engine correctly.
🤣 Yeah he said that was a no go LOL. But yeah a lot goes into it for sure. He's well worth the money to me though.
Does he sell 347 s
Yes he does
Why not invest in a 351?
For me 3 reasons. 1. Retain the stock hood. 2. Don't use drop motor mounts 3. Money (I already owned the 302 block)
4.125 bore X 3.250 stroke X 5.500 rod is the better 347...
and yes...a proper 1.075 piston can be had without put'n the pin thru the oil ring...
Yes, 100% percent. Adam showed me some different types of pistons for 331 and 347 off camera as well.
Nice!!
Thanks Frank!
@@GearHead704 think you'll be happy with the 347.
Well Matt i can see $$$$$$. Very nice.
Always gotta spend that money LOL
No replacement for displacement!!!

Could Adam build an engine that’s not technically legal for smog in California, and ship it there?

331 for the revs. Chinese parts suck!!! It’s like playing Russian roulette with your engine
