It looks to me like it has an 'early' style intake manifold on this 'late' engine. If so, I'd be concerned about how the engine will breathe like 19Fordy asks above, although it appears that oil can be added thru the blocked-off fuel pump stand. Ask the owner if the engine has been equipped with a PCV system of any sort. It may help you to review an article I just posted a few days ago explaining this situation with an 8BA in great detail. Click the link below, and good luck...nice looking truck, overall! DD
