Hello guys I'm new to this forum, I have a 97 grand prix GT that the engine just went out. I have purchased a 01 SSEi engine with 50K miles and will be putting it in shortly. I want to add headers, cam, intake, smaller SC pulley and possibly some head work. I will also be rebuilding the trans. advice would be great, also does anyone use a 3" pulley? I see lots of 3.4" and 3.2" but not to many 3" is it to much stress on the engine?
