Looking for info on building all out GMC 302 for 37 Chevy Coupe. High performance more important than streetability. Have accumulated several engines and performance components. Interested in stroker info, cyl. head modifications, possible blower info and has anyone ever converted parts from 8 cyl Hilborn injectors (cut down) for 3 port use on this engine, if so, would single round port injector or dual rectangular (like V8 smallblock) necked down to round port be preffered and how would you determine size in order to maintain best velocity. I recall that someone previously posted info as to poor machining tolerances on these engines but cannot find now, anyone know who or where? Also, anybody have roller lifters for GMC? Thats enough for now, Thanks all.
