it's an automatic. so i'm guessing the 3.73's will do. now in your opinion, is it worth sinking the gears into it? sorry for all the questions, but these are just things i would really appreciate answered, i know alot about my stock LT1 but when it comes to upgrades, i don't know what good brands there are, and what the best upgrades are for the most horsepower and little cash. so thanks

 

one last question. on my Z28 right now i have 255-50-16's. the front wheels are toast because of a needed alignment that never happened. I want these nice wide tires again, but the only ones i can find that aren't foreign are bfgoodrich and they have terrible reviews. anyone know a nice wide tire for summer/rain driving???
