I was scrounging around the pick n pull, and found two caprices', one with a 4.3 baby LT, and found one with a 5.7 LT1. I have a 96 k1500, and I know the vortec heads are just a cheap LT head. Has anyone tried to swap heads from an LT to a sbc before? I know the intake wont work, but if the heads will, I've got a L31 in the machine shop now, and would be a cheap way to upgrade the heads other than buying a new set of aluminum heads. Just a thought.
