Guy with a Chevy

I am wanting to spend up to 700ish for a set of 4.000 bore pistons but I am unsure of the wrist pin size and the compression height of the stock L76 piston. I know the one way to find out is tear it down all the way. I have been unable to find anything on the info and I am pretty good a searching please help!

The easy route would be to tell me what pistons would work with my L76 and 832 heads that have been milled .030 and a .550 lift cam(Torkinator) and possibly come with rings?!

Preferably I am looking for -2cc pistons but I think -4cc will work just unsure of wrist pin size (0.927 or 0.9431? ) and C.H(1.326?).

Would the set above -4 or +4 to the combustion chamber?

Are you wanting to use aftermarket or oem rods?

The OEM rods that I believe have to be sized from .927 to .945 if I want to use the set of pistons above correct?

Or should I expect my rod bushings to be .941?

Aftermarket rods are .927
gen 4 (floating) rods are .943
gen 3 (press fit) are .945

Summit has a guide that explains in detail. It’s for their brand piston, but still informative.

I'm selling a set of Wiseco pistons with .927 tool steel wrist pins and K1 rods that work with 4.000" bore, 6.098, 3.622. Bought them for my 6.0 with LS3 heads and never used them. Still packaged up in the boxes.
