My brother has a 1988 1500 GMC truck that he uses for plowing it has a tired 4.3 liter v6 in it and we are thinking about dropping in a tree-fiddy TBI but I can't find what the 5 speed manual (aluminum case) tranny is. I want to make sure it will hold up to a 350 before I go droppin' it in there.

Anyone got any sites with the info on these things. I searched but came up empty.


Thanks
