im building a mild build for my 94 z28. i have a new set of stock replacement rods. a block to have machined. ive found a set of pistons that are new in the box but it says they are 383 pistons. can i use the pistons on a stock crank build? if not if i brought a 383 crank is it possible to use the stock connecting rods? thanks Dustyn

 

You need to see what the compression height of the pistons is, and that will tell you if you can use your rods for a 383 build, but the pistons are going to be too short for a 350 build with stock rods and with longer rods compression might still be too low..

 

okay ill check on that thanks a lot

 

this might help you

page down to where it says Small Block Chevy Compression Height and it has a matrix for rods vs. strokes and gives compression height.
