I'm rebuilding my 1991 Chevy truck with the stock TBI 350. I'm trying to get it around 400 HP or better, but I'm having some trouble finding the compatable parts. I'm getting Dart large valve, high flow heads with angled plugs, Wiseco flat top pistons for a 10:1 compression ratio. Does anyone know of a site or person that has built a Hi-po TBI engine that I could copy or get some ideas from? The intake and fuel injection seems to be my biggest obstacle. Thanks for any help.
