    I live in smog town (San Diego) so that's out!

    Doing the following will help:

    Different exhaust(get rid of that water heater sized restrictive muffler)
    K&N filter and less restrictive tube
    Computer tune (Diablo, Hypertech, custom)

    Those throttle body spacers pretty much do zero, there is no evidence to back up the claim that they increase HP and torque.

    I did headers, exhaust (no muffler but I kept the H pipe), spectre intake, cam swap and springs (not installed yet) throttle body spacer, custom tune from diablo and maybe eventually I'll do a dyno tune, 373 gearing and smaller, lighter rims and low pro tires. Once the cam is in and the tune is perfected I will, without a doubt, smoke an SS. The next mod would be built heads that are port matched to the engine. This truck is getting very impressive and sounds AMAZING! I can't wait for the cam to go on it.
