Jim,
I may be wrong, but I think you have the Z-11 engine confused with the 427 Mystery Engine. The Z-11 carries the same block casting number as all the other 409 passenger production blocks in '63, but it's stroked. The heads retain exactly the same valve arrangement as the 409; they're just taller, with raised ports. (That's not to say they're common) Verne |
