i mean headers, y-pipe - everything that is not behind the cat. what trans do you have, a t56 or 4L60E? the stock one from your 85 TA wont work unless you are running a carb and can get the TV cable set up properly. and I don't know if the flex plate and t/c will work. might, not sure.
do the v8, it's cool. but don't try to justify it with MPG.
