There has been a lot of research done on the sbf. i believe i watched this on horse power tv show and they did a engine with minimal cost. around 1100$. And came up with a 400 hp engine. that was with rods and mains, heads, intake, headers, and i think they did 373 gears. it was real cheap for that amount of hp.
I have a 302 i am considering putting in my 47 dodge pickup rat rod. it is a 95, ho roller motor.i am going to put on a set of old style 289 heads to build compressiom
Change the cam, intake and distributor cause the efi stuff will mot work without a computer.
