I noticed you ask about a pulley and E85. I would highly recommend giving www.raceprovenmotorsports.net. I'm not going to talk bad about another shop but I will say that anyone can install parts on our cars but it takes a pro to tune it. If you call them tell Bill I told you to call. My name is Guy. Bill handles the phone and price quotes and the owner Fran tunes the vehicles.. Great guys and great shop.. By the way your car looks great. White Vettes are best color..
