I know this has been discussed many times and I have searched and read a lot of great threads but I still dont know what I should do. I have a pair of Romeo PI Heads, and PI Intake Manifold for starters. I am debating on going two ways. (1) PI Heads + Intake Manifold with Mac LT's, shorty offroad H pipe, and diablo predator. OR (2) PI Heads + Intake Manifold with 4.10's, aluminum driveshaft, offroad H-Pipe, and diablo predator. Which will give me the best 1/4 mile slip. I just dont know which way to go. Any opinions are welcome. Thanks
