I still don't understand this one. There must be thousands of Chevelles out there that have turned 4000 rpm in high gear (1:1) many times on stock driveshafts. Munice + 12-bolt = stock length shaft, right? The factory offered 4:10s which would put the driveshaft at that speed barely above legal posted speed limits. I wonder what was going on in your car that made it spit out the shaft?
