Check into the mods I've done. I've thrashed a fair share of LS1's. Down low and up high. My car is running stronger now than when I first put on the mods. It keeps getting better. There's been a lot of heated discussion with regard to LS1 Camaros and TA's. With my mods, I've only been able to beat automatic trans LS1's. 6spd Camaros and WS6 TA's with intake and exhaust work are(I'm sorry to say), virtually unbeatable at any speed. You would need to be well into the twelves to put up a good fight. However, you do have a good shot at nailing that Mustang, especially if it's stock and an automatic) 5spd and an exhaust are a little tougher. I hope I didn't bum you out. Let us know what happened with the stang. Put some race gas in before you go at it.
