i have ah 98 trans am i think its ah 5.7l LS1 ...and i wanted to get the upgrades to make it a formula...what is it the i have to get and how much would it cost .....
If its a 98, it's got the LS1. But motorwise, theres no difference in the T/A or the Formula. Basically the Formula is scaled down Trans Am. Different hatch/front clip.
