Hey I'm thinkin bout trading my 98 gt 4.6l for a 86 gt 5.0 . Does this sound like a equal trade?? My 98 does have cold air intake,bbk exhaust, bbk throttle bottle ,new door panels,door sill plates,halo headlights. The 86 gt is bored from 304 to 306 and is a five speed and has lower miles and has a cold air intake. I just wanna make the right trade.thanks alot!
