Well, So far myself, I have gone 10.50@ 137 mph on 315's and 93 octane pumpgas. Unfortunatly, that was not a complete pass because I blew up my torque converter. All the sudden it would just zing right to the rev limiter. I was running a 9" and now had to swap to a 10". I am hoping to get to the track sometime in the next month or two and see what it really runs. I am hoping for 9's @ about 150 mph, but I will have to wait and see. Honestly, I am pretty happy with the only slip I have, I didn't think that was to bad given the situation!
