Check the cross-bolts visible just above the pan
By P - 11/20/2001 10:48:08 AM; IP 66.89.75.42
If it's any of the various versions of the 427 it "should" have crossbolted mains, which are visible above the oil pan on each side.

There have been some rumors and some light evidence that there were some special order industrial versions of the 427 that might have been built without the 4-bolt (cross-bolted) mains, however it would be considered a real rarity if you found one. There's also quite a lot of published info out there about the 2-bolt 427 that was put in the 1968 Cougar, but despite the two articles I have in my files, I am convinced (by Royce and others) that this is not correct information.

I’d think the easiest way to tell a 427 would be to look at the cross bolted mains, and then start looking at other things to be sure you didn’t have a late model 406, which also had the cross bolts. There are “rumors” that a few 390’s had cross bolts, but based on what I’ve heard, these would have been a small handful sent to Holman Moody, or even prepared by Holman, and if they exist at all, they were never put on the street. So basically, if it doesn't have the cross bolts, it's not a 427.
