Hi I have a 5.7 vortec in my Chevy truck it's
knocking from the bottom end can I replace it with
a350 small block 4 bolt main if I put my heads and
intake on it?
what year is the block you want to install?
Reason being MStamps is asking is the valley is designed for lifer guides as the vortec is a roller cam motor. Need a block from 1996 and up.
