318 poly push button transmission
Actually... no. not really. I already have 2 spare 440s, 2 spare big block push buttons transmissions with correct driveshafts and a spare original 64 big block radiator. The 318 poly has to be rebuilt regardless. For now, I'm swapping in the running spare 318 poly I have. But I want to eventually rebuild the original engine but poly rebuild costs are no joke, 3 times that of a 440. custom pistons are required and I've been quoted anywhere from 1100 to 1500 alone for those. My forged pistons for my 440 were barely 400.. with rings.
why custom pistons?
