The GT-40 engine up top has a reproduction Shelby block. You can tell because the Shelby blocks have two side bolts per cap, where original Ford 427 blocks only have one.
Yeah I know... Call me the Klay of Ford engines. I'm a detail Nazi - Eeet must be correckt!
The quick way to tell if it is an FE engine is to look at the intake manifold and valve covers. The FE intake goes under the valve covers. If the valve covers are off you can see the pushrod holes going through the intake and not the head. Very distinctive feature of the FE. Same if it is the little 332 or the big 428.
