Im thinking about buying stage 3 patriot heads, stage 3 comp cams,BBK headers, Pro performance intake manifold, plenum and tb intake, valve springs, in a few months. I already have a diablochip, cold air intake, 3.73, magnaflow exhaust x pipe w/ no cats, short shift, and subframe connecters. What else do do i need for this setup or add to it. And what do you think my 1/4 times would be around.
