Something interesting about the blocks, Mr Hoover told me that when Packard went out of business Chrysler bought a bunch of tooling and the bore spacing of the B engine actually came from Packard. Thank God they were big powerful cars or we would all be screwed.



Bore spacing of the Packard V-8 was 5 inches; big-block/hemi mopar is 4.80

I have several Packard V-8's; their general layout is more closely related to the early Olds/Cadillac/Studebaker V-8's than to the Mopar wedge V-8's. I can't imagine what Packard V-8 tooling could have been used on any Mopar engine.
