Helping a friend build a '66 "big car" 389 that will go into his '65 GTO with a 4 speed and a 3.23 rear gear. All the machine work was done previously, and it was never assembled. I checked out the block, crank, rods, etc. and they all checked out fine. Thing is, he had cheapy flat top pistons pressed on to the stock resized/reconditioned rods. He is going to ditch the pistons and run some Ross custom pistons with a dish to lower his compression a bit. He is also going with a Comp Cams 268H cam. He insists on running his "junk" 092 heads (which are redone and check out). The car will be street driven only, with no track use. The BIG QUESTION: What connecting rods to use? The originals, or, as cheap as they are now, some aftermarkets?? He has to get the pistons pressed off, pressed on again anyway, so what do you think? Floating or pressed pins? Thanks..............
