It is a 1974 duster, original 318 car but the original 318 is locked solid, so I took the 318 out and put it on a tire in the garage, pending autopsy.
Then I put a strong running 360 out of a 1977 Chrysler Newport, in the duster. When it was in the Newport it ran very strong and it's a factory 4 bbl. Engine.
Unfortunately the Newport was demolition derbird, parted and crushed. It wasn't mine or I would have saved it for as nice and original it was. I was just happy to get the engine and run.
