Ok... here is the deal... I went drag racing on saturday, and ran my stock 140,000 mile LT1 to red line on everyshift.... so problems my first pass, but my second pass was a diff issue. 1st gear wnt great, grabbed second with no problem, ran it to red, then when grabbing for third, I found first again... the car bucked violently, and I stomped the clutch back in.... i actually shook one of my filter elements loose from my CAI on the track. Car drove fine, and I babied it home.... I have a dual centerforce clutch in it and a 410 posi 10bolt with TA girdle... Car seemed fine all the way home, All 6 gears went in and out pefectly, and the clutch feels ok..... Wondering if anyone had any insight on what problems I may be looking at down the road from that incident, any help or past similar experiences would be greatly appreciated.... THANKYOU....

When you shift into 1st from 2nd, you increase RPM by almost 50%. Shifting at 5,800RPM in 2nd puts you at 8,670RPM in 1st. Letting the clutch out caused a giant engine brake, and its not likely you reached that high an RPM. Most likely damage could be the pushrods, and other components in the valve train.
I managed to do it more than once, and never had a problem.Fred
