I think its got stock heads on it. The P/O said they were aluminum, and they definately arent. So i bet its in the high 13's to low 14's currently. I took it for a spin the other day. Its hard for me to compare it to my car since i had the 3.08 gears and he has the 3.73's. But my car just seems to pull harder from 1-4k, but when you get in the upper rpm area his feels like it has more pull. Mine dies at 5k and falls on its face. I was running almost a 14 in the quarter 2 years ago, now i installed my rear with 3.73's so it should be quicker. Cant wait till i get mine on the road, that will be the real test..
