Heres the deal, Up here, our tracks are pure clay, and hard as frig, and bite like a doberman on a ribsteak; and our drags are big and heavy. Ive been runnin my 550 RWHP ZF6 truck with a dual disk clutch with limited success. If im up to weight, i cant get the drag moving, it pulls the engine down from 4200 and it down and stalls. This is in 3rd gear low range. If i run lighter weight it will spin off the get go and stop at 100 feet cause it wont hook right, and it usually bounces like a bugger. Yesterday was the last straw. All the 4x4 mod guys (gasser) around here run autos of some sort, cause they have the same problem. One guy even runs a BRT converter drive into a profab reverser case with pretty good results. I have a new truck, this will just be a toy, So i was thinking of running a powerglide with a 2400 rpm or so converter and a dropbox. The powerglide can be built to take a whuppin for less than the allison, and i figure i can get out of the hole in low and shift it to high for the run home. Whats your thoughts on this?
