There are politics for sure but in spite of the racers trying to protect themselves from the AHFS these cars have been running for 50 years and are pretty well sorted out at this point.The NHRA factors are pretty good and if anything they are underfactored. The Thermoquad and mani are both excellent pieces compared to the AVS and it's mani. A 64 Ply 383 and street wedge are almost identical in rating with the 383 at 292 and the 426 at 291, same carb, mani type, cam and heads and they run almost the same.
