Bought an 89 Gt today. It has had some work done including e303 cam crower roller rockers, 58cc ported heads Car Tech intake with 70mm mass air flow, bbk air intake, flowmasters and Centerforse clutch. It still has factory headers. I plan to buy some shorties. How difficult install is the equal length bbk's? Would it better to just go U/E? It has 355 gears and rebuiltT5. I need some interior pieces so if your close to Tulsa and have gray ashtray lid and the whole arm rest thing as well as the seat belt covers pm me. I will get some pics up later. The Car Tech intake is pretty cool. The car runs very strong.
