my 84 z h.o. has original 305, very low miled. I've a newly rebuilt 327 from vette but am not gonna use it. I,ve got all edelbrock kit, cam, 600cfm carb, performer intake, Upgraded Accel hei, shorty headers and 2.5 inch exhaust flowmaster, car has factory 3.73 rear as well. Its a clean straight car but with all this thats gonn be done can I squeeze 300 hp out of it? Im not planning on head work for it as low miled asit is.
