Well a few months ago I bought myself a truck from a guy who got it at an estate sale.
1974 W200 with a 360, NP 435 manual transmission, 205 divorced transfer case, Drum brake Dana 44 Up front and Dana 60 out back.
nice! Wow, that bed! What did he haul? cotton balls? The PO either never hauled anything, and/or it was covered up all the time. It looks virgin!
there's nothing really wrong with the stock 360 4bbl manifold, other than being heavy.
