My dad has a 98 trans am auto. How much horsepower will a stock driveline hold trans, rear, etc... Also what is the easisest way to get 500 hp without nos. Thanks in advance fellas

 

a big heads and cam package with all bolt ons will only net you around 450-470 rwhp. Because one its an auto and 2 i know hes going to get a torque converter which kills hp but makes up for it at the track. Easiest 500hp will be nitrous
