I know this has been asked a million times before, but my searches aren't turning up much. I have a 91 LX 5.0, with all the current mods below. In late spring or early summer I plan on getting a cold air intake, 70 or 75mm throttle body, cobra intake, either cast iron gt-40 heads or aluminum y or x-303 heads, if I can afford it. Also an e-303 cam, I want to stay emissions legal. I'm also doing a heavy duty rear sway bar, strange adjustable shocks and struts, and possibly poly-urethane bushings in my suspension. Around how much power is this going to make at the rear wheels, and what times could I roughly be looking at? I'm an alright driver, and the car is almost 100% street. Thanks for any help.
