That is a 426 max wedge with a 413 dual point distributor. All original with 400 actual miles on the whole top end. I sold it and my 63 fury convertible to a guy in Lexington to buy some ebody stuff. Every nut and bolt was period correct. It was 12.5/1 620 lift cam,
The guy pressed me for a while to covet my stuff. But I got more. I'm a mopar poor rich kid.
I truley like it this way though. I enjoy the toys I have stashed away for decades
