Block was decked to the top of the pistons.

That's the difference-most truck FE engines have the piston located .112" down the bore. Earlier car 390's were from .005" to .020" down the bore.

That sounds a little high at .112" ... I used a '74 truck 360 block for my 390 build and the pistons were about .020-.030" below the deck when I took it apart... the motor was OEM, never rebuilt.

Sounds fishy...

An afterthought... that might be true for the FT heavy-duty truck motors, they have some very low compression like 7.x:1
