427 mystery motor?

[Clem Z.]

if the lifter bores are all in line like a small

block chevy it is a "mystery" engine used by GM in 1963 before the big block mark IV was mass produced. the production mark IV engines have the intake and exhaust lifter bores on 2 different angles. the inline lifter bores on the "mystery" cause a bad alignment of the exhaust push rods causing durability problems while under race conditions

Why not just post some pictures here for everyone to see?

It is easy. You can post one picture at a time. You need a web host, but those are easy and you may already have one with your email service. If not, go to tinypic.com and upload the pictures from your computer. It is free.
