OkI have a 91 GT. i wanna play with it on the streets, and i need to have it pass smog! I really want to get a 347 stroker kit, my block is already .30 over it has aluminum pistions, and a stock cam from what i know. would you buy a motor just to pass smog and build one for later? I am just so confused on what to do what what good stuff will pass emision!!! Would a 347, trick flow heads, mild cam, manifold be much hp? ...maybe supercharger? just any help of what i could do!!! and still pass smog! ;-) and keep in mind i want some nice hp! thanks
