Re: 727 to 518 swap...

I didn't think about the A500. How is it strength-wise though? Stronger than a stock AW4? I'd run an AW4 behind a stock low compression 360 as long as it was pretty much stock, maybe a mild cam and 600 4V. Don't know about putting it in a GW and towing a heavy load though. I'd definitely think the AW4 would be up to the taks of just motoring a GW around though. I've had no problems with mine behind a 245 hp/300+ lb/ft 4.6L, even towing about a 3,000 pound load (trailer and load total 3,000).

The OD for the 518 is totally in the tailshaft housing. By looks alone it appears that one could possibly take an AMC 727 case and use the 518 output shaft, OD unit, and tailshaft housing to make an AMC OD trans. The 518 is 3.5" longer and would require modifying the rear crossmember (detailed on the site), but I wonder if this is possible? Or is adapting to the more plentiful GM 700R4 cheaper as well as easier??
