I always draw on my dirt track experience, where things got exciting in a hurry and stayed that way. A crossmember under that tailshaft housing with a beefy rubber mount would handle driveshaft torque better, but that might not be a concern unless you're planning to hammer the throttle repeatedly in 2nd. gear going into a 4.56 locker rear end. We would cycle from 3k RPM to 7K at least twice a lap, on a track surface that resembled a washboard. That stresses things in a way that a street machine never sees. Running that Muncie 4 speed in 3rd. gear instead of 2nd. would split the case wide open at times. We changed the final drive ratio to adapt the RPM to slightly different track lengths- - - -4.56 on a "short quarter mile" measured around the outside wall, and a "long quarter" measured around the infield got a 4.11. Both running against 2nd. gear. Jerry
