" From: "Garry Nordstrom" <gasnordstrom@xxxxxxxxxxx> " " still waiting for guidance in hooking a tranny to my 343 settting in CJ8 surprised nobody else has chipped in... 400hp +/- iirc? the t170-series toploaders should be alright, but - don't they have aluminum cases? a swap to a ford iron case would be a good move. a steel or iron bellhousing might also not be amiss. if you're leaning toward an auto, for that hp and with the trailer you want to pull a tf727 might not be overkill. a built 998 or 999/32rh might be enough, especially if your towing is only occasional. it's probably spendy, but something was posted recently about someone who's doing the a518/46rh/47rh for amcs; the extra gear would let you gear low for pulling and still have reasonable cruising rpms, though it matters less in a 4x4 with a low range. it's also longer than the 3sp autos, but a cj8 should have the room for it. and of course you'll need a tranny cooler for any of them. harrel mentioned the th700r4; it can certainly be built for 400hp and i believe it can also be adapted to your t/c if you don't want to run a gm one, and it would have the same gearing advantage as the a518. check advance adapters. for road use, both the dana 44 and amc20 rears should be strong enough; you won't be running monster tires or shock-loading them bouncing over rocks. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought _______________________________________________ AMC-list mailing list AMC-list@xxxxxxxxxxxx http://list.amc-list.com/listinfo.cgi/amc-list-amc-list.com
