Yesterday I installed a 327 with a Muncie transmission in my 1967 Coupe. It had originally been 250 Six Cylinder with a Powerglide. The install seemed to be going great and the motor mounts lined up and are bolted down. The issue is with the transmission. The mounting location on the transmission is about 2 inches short of the crossmember and the transmission mount. See photo. From everything I've seen, there is only one crossmember for a small block installation, no matter if it's a manual or automatic transmission. While this car started life as a 6 cylinder with a Powerglide, it looks like the crossmember would still bethe same. What am I missing? Why doesn't my transmission line up with the crossmember transmission mount? The Muncie 4-Speed transmission has the 3885010 case with a 3846429 tail shaft. I've also compared the 429 tail shaft to a 3857584 tail shaft (difference as to where the speedometer cable is attached), but they seem to measure exactly the same in terms of length and position of transmission mounting. Is this potentially a Muncie vs Saginaw 4-Speed transmission issue?? Any thoughts appreciated!!
