I'll have to check out the block a little more closely. The engine is out of the car and apart so I can get a better look at it. It still has the crankshaft in it and is a C4AE-B 427 crankshaft. The motor was definately rebuilt at one time and used in a Cobra. I received it with a snapped rod! Other than the obvious, are there any tell tale signs of align boring that are easy to spot in the FE's. I really appreciate the help here in this forum. Thanks!!!
