Here is what I suggest. But first. Is your car 3000 with you or by it's self? How much do you weigh?
Anyhow, you did not give a budget.
I like NA, so it's a R3 9.56 deck siamese 4.185 bore 11:1 compression with a callies 4.25 stroke crank, Indy -1 245 CNC heads/manifold and a good roller cam and you are set. Plus some good headers / ign and carb.
