went to the track today. Car has a 434 small block with 18 DEGREE heads. t-350 trans with 430 gear. Its a 1980 grand prix. Motor has 35 runs on it and has ran perfect till today. First time run went 9.19 @ 146 mph. then after that it went 9.29. It falls over real hard at the top end of 1st gear. I shift at 7000rpm 1st and 2nd gear and goes threw at 7000. Today the last 3 runs it would get to 6700rpm in 1st gear and lay over hard then after i shifted 2nd to 3rd it pulled hard as it ever did. So what would cause this to happen only at the top end of 1st gear and not the rest of the run???? Like I said it ran great up untill after my first time run today. Thanks for all your input on this...........Rob
