I have a 1976 chevy 350ci, 4-bolt main I am working on. The engine is low milage and in good shape. I will be putting it in a 1972 chevelle, which I want to be streetable. The heads are stock 75cc (1.72 intake, 1.50 exhaust). Can I get 300+ HP using these heads and upgrading cam, intake, and carb ? If so, what should the combo of cam, intake, and carb be ? Im planning on headers for exhaust. Any advice is appreciated.
