I am putting together a 350 chevy engine to go into my 1972 chevelle. I am looking to get 330+ horsepower. The engine is a 1976 4-bolt and the lower end is in great shape. The heads I am planning to use are stock 58cc (1.84 intake, 1.50 exhaust). I was going to go with an edelbrock performer manifold, a 650cfm carb and a beefed up cam (say a 270). Am I on the right track ?
