Just thinking about the possibility of using a 1989 truck version of a 700R4 behind my big block street machine. The trans was in my 1989 1/2 ton Suburban and gave no trouble at all pulling a 32' camper. I recently had the trans rebuilt (preventative maintenance) and then ended up junking the body because of rust issues. The trans is non-electronic. I see that TCI has an adapter for this swap. Part number 149260 is 1/4" thick for the 6 bolt crank. Has anybody done this swap? The trans seems no larger than the 727 in the car now. Looks like the linkage from the GM throttle body to the trans can be easily adapted to my carbs.
