I made a post the other night trying to identify what kind of FE block I have...Here's a recap:

C7ME-A
X in lifter valley
4.050" bore
4-bolt engine mount
Pipe plugs between back two freeze plugs

The FE reference book I bought the other day said that only FT blocks had 4-bolt engine mounts...is this correct? It said that would be an easy way to tell if you had a truck block or not. I know very little about FE engines...the only engines I've ever touched were small blocks...so are the pipe plugs between the freeze plugs drain plugs?

Anyway, I did a drill bit test on my supposed 390...here's what I got.

Passenger Side - Front To Rear

1-2: ((4.62-4.05-(17/64))/2)=.152
2-3: (4.62-4.05-.25)/2=.160
3-4: ((4.62-4.05-(17/64))/2)=.152

Driver Side - Front To Rear

5-6: ((4.62-4.05-(15/64))/2)=.167
6-7: ((4.62-4.05-(17/64))/2)=.152
7-8: ((4.62-4.05-(17/64))/2)=.152

So that's what I'm looking at now...the FE forum says that if you can fit a 17/64 bit in between, you should be fine to go 80 thou over...it looks like I should be fine...right?

A good friend of my dad's does industrial inspecting...I'm gonna get him to come over and ultrasound the block after I get it cleaned up...

Does it look like I'm in good shape to you guys so far?
