Sure did. NOS Chrysler pieces. Real nice set.

New one on the right, old 7.5:1 on the left.

Yes, but remember, it is going to end up displacing 354 cubes. I plan on a 5500 max, even though it will have a solid camshaft.

What I would like to know is how the hell did UPS manage to break a cast iron manifold?!! :roll: It was two fold and actually ended up being a good thing. First the shipper packed it good. Not great, just good. Secondly, UPS somehow dropped it on concrete. The concrete powder was still on the box a...

Super nice stand David. You really have some skills there.

Sure does help. My plans are to get two of the 352 CFM.

Here is my mannyfold after being broken by UPS, repaired by a good friend cleaned primed and painted. Those are carb adapters that will allow me to run 2 GM 2GC two barrel carbs. Since they come in a array of flow numbers, all the way to 600 CFM each, I should have no trouble finding a pair to zoom ...

Great job. So when do they go into production?

If they would just do that with the Wrangler, they'd have a winner.

Nope. It's still available. I actually went to look at it and chew the fat with the guy. It's real complete. He seems like a straight shooter too. He builds rods. Gotta lotta cool stuff.

Thanks George. But like I said, unless it sonic tests to where I can go over 354 STD, it's not gonna get bored that far. I will just trade off these NOS pistons for some 331 pistons, or sell them outright. Thanks for all the info yall. If I had the choice of .030 & 8.5 vs maxed out & 9:1, I...

Naw man. Don't say all that. lol Hell, if anybody's the dipshit here, it's me. LOL I'm the ignorant newbie. Yall have really helped me here and I do appreciate it. ....also had I known we had castin number info I wouldda looked. LOL

So now I'm kunfrooshed. Which block is it? Everything I find on line says 55-56 331. But I only find that number one or two places.

Here is the number as cast on the block. 1619629-2

Not seein it where dangit? What reference do yall have? lol

I would never think about going to 4". And I will not go to the 354 bore size without a good sonic check. And I mean good enough to go 354 over size. I want to keep this a while. Thanks for that info George. Everything I had found showed 331 truck only. what literature do you have, btw?

Casting # 1619629-2 Date code C 14 6 and then W It also has the W cast into the side of the block as well.

The one on the right.

George wrote:In theory, if it has 354 casting #, and it really is just an underbored 354 w/o any wall thickness adjustments, you should be able to bore to 4.000. 331s that were 55 & earlier shouldn't go past 354 std bore. A 354 typically can go to 4.00

Where does the '56 331 truck block fit in that theory?

Dang man. Goin with a chebbie bore size is gonna slow it down. LOL

Unless the bores are badly rusted and corroded on the water jacket side or there's an unusual amount of core shift, a '56 331 heavy-truck block should be perfectly safe taken out to the 354 3.94 bore size. Most standard passenger car 331 blocks would be pretty thin and about maxed out, bored to 3.9...

Well I will certainly find out when I have mine sonic checked. With all that I have read, it varies from block to block and there is no hard and fast rule. Take the engine above. It was into the water jacket, yet was a running engine. Obviously, it had cylinder support. At 4.040, he is .022750 OVER ...

I got me some pistons. Old on the left. New on the right.

mart, you gotta PM. Let me know what you think.

But none of the cars sound good anymore. When the Shelby GT 500 came back out a few years ago, one rode by us one day in Macon. My son was havin a fit talkin about how "mean" it sounded. I could barely hear it go by. Well.....just so happens one of my old friends happens to be a Mustang gu...
