i only got a street tune thus far, yet i am on a limited budget, but i may be able to afford some new pistons and rods here soon.
i was told the b heads flow better, but only slightly. From what i hear no one makes an aftermarket intake manifold for my 96 that is decently priced.
i have a nitrous kit waiting for it, but i wanted to have the motor running good before hand. I am just so lost with these 4.6 motors it's not even funny. I have to rely on the info i get from others to even think about what i have to do next.

to answer hurst:
i have an accufab TB / c&l intake tube/ mac inside the fender cai
im n/a for now. i also still have the IMRC's.
not sure if cams were degreed or not.
i had Genium performance put the cams in about a yr or more ago.

im just very lost with the car right now and hate the loss of power...
