Looking to possibly build a 331 or 347 stroker for my 92' LX. I just put a brand new GT40 crate motor in from Ford. The parts on the current motor are: GT40 aluminum heads, E cam, Cobra upper & lower intake, 30 lb injectors, 75 MM mass air, 70MM throttle body, shorty headers, 255lph fuel pump, Vortech SC 6lbs of boost. My question is what parts can I use of my motor now for the new setup? I want to keep the car SC'd but I might upgrade to a S trim. I've heard that I can use the same heads as well as intake, what else. Also 331 or 347? Car is just a weekend toy, but I want it to be reliable and streetable. Give me some suggestions please.
