Stroker kit Eagle B13454E030 383 Balanced
Hi,
I have a friend with a 1971, SBC 350/270, TH400 and 3.08 rear.
He needs a new short block, the top end is good and brand new.
The top end is, AFR 195 64cc, Comp Cams EFI roller cam, 1.6 rocker arms, Team G 7530 and EZ-EFI 1.0, 1 5/8" headers, 2½" exhaust.
He is thinking about sending the block for 0.030" over, and buy Eagle B13454E030 Chevrolet 383 Balanced Rotating Assembly fit Chevrolet.
As I see it, then it is a internal balanced, and that is what he wants
I can see it will be 10.28:1/8.37:1 and 0.040 quench with 1094 head gasket.
Any comments to the stroker kit/engine setup?

How did you come up with this compression Ratio, do you know what the cc of the Pistons that will be used is??

Why the hypereutectic pistons? Build a bulletproof bottom end for what ever he may decide to throw at it later. From what I've read, the hyper pistons are not very resistant to detonation. Hopefully we never get there, but Mr. Murphy does come around from time to time.

I think I'm now officially confused at the purpose of this thread.
I thought it was to get feedback on the stroker kit; it sounds like you're saying he's already going to get this kit and you're not actually looking for feedback as it's not your money?
If I'm misunderstanding and you ARE looking for feedback. I'd agree that for very similar money he can get a stroker kit with a cast crank but forged 4032 pistons; that would be a better way to go.
The 383 crank is going to put additional side-loading on the cylinder bore wall if the crank throw changes but the rod length doesn't and IMHO, if you're going through the effort to get a new bottom-end it would be penny wise and pound foolish to not focus on longevity between required rebuilds. A 6" rod can help reduce the side-loading on the walls.
I can't tell from the details on Summit / Jegs what the ring pack looks like but it's a good opportunity to go with a quality, modern thinner ring pack to reduce friction -not a "thin" or "ultra thin" ring pack, simply what qualifies for "normal" today vs. 1960. Improved torque and fuel economy and reduced wall wear and oil consumption can result from a good modern ring pack.

The stroker kit is not bought yet, I am (this mean a friend of mine) is looking for feedback about, is this a "ok" set for the money.
He is not looking for 500+ hp, no racing, the only reason he is going 383 is the his 350 short block is toast.
Any recommendations for alterative parts are welcome.
