I have a 79 corvette that I am putting a 95 Impala SS LT1 engine and trans in. The car has stock suspension, and braking. It also has a 3.83 posi trac rear end which is also stock. I have a gm replacement crate engine with a th350 that puts maybe 180 to the wheels. I am looking for around 350hp to the wheels. I will be making a custom ram air/cowl induction cold air intake. The LT1 is all stock same as the 4L60E. I will be using my hooker gen 1 long tube headers on the car with 2.5 inch exhaust. I have read that I should start with valve springs and 1.6 ratio roller rockers. What should I do next to get around 350 rwhp? I am sure all of this has been covered before, but it gets confusing reading so many different threads. Thanks for the help, sorry for the redundancy.
