i have a 1985 grand prix le with a 305, so far i have put an open element air cleaner, and an accel supercoil with matching cap and rotor. im wondering what i can do to make it faster. i just picked up the car for $400 locally. i dont want to do an engine swap for 2 reasons, 1 i live in an emissions testing county, and 2 the engine was replaced with a brand new jasper 305 in 2000. i know alot of parts from monte carlos and other g-bodys are compatible but i was curious if suspension parts would be the same because i want to do something about this body roll this stock suspension has as well. also, what kinda HP came stock in these cars.
