I am going to be building a new motor for my mighty max. I am hoping to build a junkyard core and continue using my truck until it is done. Then I'm going to rebuild the one in the truck for a spare in storage.

My question is I have an 88 mighty max 4wd 5 speed and I found a 2.6 in an 88 dodge raider automatic in a local junk yard. Is there a difference in the crank between a 5 speed and automatic? Any other difference that would cause issues? Thank you
