I have an '86(?) Montero with a bad engine (spun bearing) and a 3-speed auto transmission. I also have a G54b engine which I feel confident I can get running well. One engine is a wide block and the other a narrow block.

How much of the bolt pattern will match between the two? That is to say, for instance, Can I get all but those two bottom bolts to match? Is it possible to re-drill some bolt holes for a better match? What are my choices?
