I Want To Build A Stroker Engine

In add to 396 sayd, Im from Brasil and here we have alcohol similar your E85, its fantastic...high compression, cheap fuel, high performance, high power. Here 95% of the high performance cars run with alcohol. Becarefull in just one thing, its hard to start cold, we usually use gas to just start in the winter time.
As the other guys sayd, If you want to buil 400 hp on a budget you can do on a high rev. 318 or on a 360. But, the main issue is the heads, try J heads or magnum heads and if you could eddy's heads.
