And here are some pictures of the 505A that Pete is talking about - with some side-by-side shots against the 404A.
I have yet to run the cam, need to build a very "special" engine for it.

And Jazzy Nelson's Coupe . . . probably the fastest drag coupe that ever ran a flathead. Jazzy ran the 404A quite a bit, but "wanted something bigger - and a secret grind" - that is when Ed made the 505 for him.
