well ive got the 350 out of my old chevy, so a free engine. i tore it all apart and im just some new heads, lifters, rv camp, new valves, ect. this was all stuff i wanted to do and then put back into the truck but im thinking ill just throw my 454, after all the goodies are in it of course, back into the chev. so i have an engine already. and im not going to lie... im a gm guy. i love the 350.
