hey sorry if i posted this in a wrong thread or what not i figure its still within the years but i just wanted to ask some of u guys who are real familiar with the grand national. my buddy has a 87 grand national. he was asking me stuff as far as performance upgrades. i told him i dont know squat bout those but i told him i can find out. he lives in ca. and we all now how emissions is. so i was just wondering what mods and brands that are real good that he can put. im sure hes not going all out 10sec. but just a few mods will help thanks.
