I have a 1980 elky and it was origionally a v6-???ci engine. The last owner swapped the engine and put a 4 speed in it. I have no idea how to tell what kind of engine or tranny it is so i can get stuff for it. Such as hurst shifter, supercharger, headers...ect. what are the necacerry things that i would probably need to know in order to get new parts for this setup? please help! i am new at this, haha and my dad says he'll help but he helped my brother fix his bronco and he didnt do anything and had no idea what he was doing!
