This isn't technically a pre-'73 question, but I hope someone can help anyways.
I have a '89 Suburban with a blown TBI 350 engine (cracked head led to valve seat rattling around in the cylinder). I have a good '85 350 that I can use to put into the Suburban. I know the heads and intake manifolds changed, but I'm not clear on any other changes. Right now I plan to get a new head, and use the good '89 head and intake on the '85 350. But I need to make sure the '89 accessories will bolt up to the '85 block. Time and budget is a little tight, which is why I would like to avoid a new/rebuilt engine or rebuilding the '89.
