Ok I know that there are better cams out there than the E303 but I am not looking for a race car just something that will move nicely when I hit the gas. I recently purchased a set of GT40 heads (3bar-not Ps) for a decent price. They are completely rebuilt never been run. I also have a Tmoss ported stock intake on the way. I was thinking of putting the e cam in while i have it apart. I have a 91 GT stock automatic with 56000 original miles on it. I just put 373s in it and a Trans go AOD reprogramming kit is going in as we speak. Will this be a decent combo to add some at least noticeable power over stock? Anyone running a similar combo right now? I was also kicking around leaving the HO cam in and throwing on a set of 1.7s? What do you guys think?
