I personnally would start with the rear axle, 3.73s and some
suspension mods. I would save the cam for when you can swap the heads, and why
waste the money on porting stock crap, just to turn around and swap them off in 6-8months
If youre AOD, the street manifold is better, if youre 5speed go with the track heat
I went 13.30-13.40s with Cobra and 65TB/75mm mass and 24lb injectors.
Stock long block, factory cam, and1.7 rollers
Just an opinion
