I took out an inline 250 and dropped in a v8 years ago and it was easy, you will need motor mounts. can't remember the the mounts on the truck worked, but you will need ne block mounts. don't remember any trouble. '79 stepside

My truck was original with a v8, the po put the 6 in. I believe the mounts on the truck worked for both the 6 and the 8. Just get in there and look at them then grab your lmc catalog and compair
