I might add the standard ratio for an M22 is 2.20 in first. You typically had to run a 4.11 to make up for that first but that in turn helped save the trans. That and the fact that muscle cars were running polyglass redlines and uniroyal tiger paws hence no hook. I popped first on my BW Super T-10 but it had a 2.88 first which is thinner. The BW Super T-10 out of a 74 vette that is now in it has a 2.43 first and has lived against my ZZ383 so far. I have done no "no lift shifts" though. I have banged at 6k though and have seen no ill effects. Torque on my engine is 460ft. lbs. and comes on high.
