OK. I finally have the money to do a motor and trans sawp, 89' d100 w/ a 3.9 v6 and 42rh, I want to swap ineither a 318 or 360. I will prob just use a new 727 or 904 from jeg's. The only thing I'm not sure about is the mounts, if I have to I'll just make some but I would prefer to buy some. Bouchillon Performance make aswap kit but it only works on small block to big block trucks. If anyone has any tips or suggestions that would be great!

 

The local junkyard has a bunch of a727's sitting on the shelf, rebuilt with torque converter, for about $700. Go with the 360. The work is the same, but you'll get more power and more potential. Just buy the OEM 360 motor mounts from Jegs or summit.
