Gary,

I believe the "mystery motor" was the canted-valve, new head-design, N.A.S.C.A.R. motor that we came to know as the 396/427/454 engine. The Z-11 was a 409 on steroids; angled top-deck block; a "combustion-chambers-in-the block" design with some really good-flowing heads and an intake manifold, the design of which emulated a tunnel-ram (raised carbs, with vertical runners delivering the charge to the heads.)

A VERY powerful engine...

The cranks may have had similar bearing parameters, and the bore-center spacing was the same, but they were two very different motors in terms of the top end.
