I saw it on CL... Nice find... Would only be better if he had a 351w to go with it too!

What brand LT's is he throwing in??? Some of the LT headers have to be adapted to fit into a 4x4. Just a heads up...

My advice on the M50D would be NOT to put a M5OD back in that lifted truck! with the 35's, a 302 w/ hotter cam, and 4.10's you'll end up breaking that M50D again in no time. Especially if you are going to use it in mud and off road! Go find a ZF542 4x4 tranny out of a small block 300 or 351w f250-f350 and you'll have a better tranny that will take the abuse of the bigger tires.
