Quote: Interestingly, the only other Chrysler exhaust manifolds even remotely similar to these did actually make it into normal production, these are the 1963 Chrysler 300J 413 Short Ram manifolds, they have the same crudely cast appearance, are HUGE, heavy, and have some similar rectangular tube shapes (like the Tri-Y's above do) as opposed to round tubes as most other big block manifolds had.
And they won't fit a b-body unless you get rid of the torsion bars.
