I have a 91 sonoma st 2.8 with some little mods mostly top end, but im deciding between a stroker kit, headers. Or just getting a 4.3 trans and a chevy small block, and headers. It would also have a bored out intake manifold for a tpi system (bored to the stock size of a 454). What you guys think based on power and price? Ohh and it has to stay manual!!!
