Thanks for all the info. I knew I came to the right place.

didn't even think of that...just cause the valve covers say 427 don't mean it is...
When I get a chance to investigate, aside from pulling the heads, anything to look for on the motor that would be a good indicator? I'll try to get some better close up shots to add to the photos. By the way, is it cool to do the pics that way? I tried a few times to add pics to the post but couldn't figure it out. So figured I'd just make a google photos album and post the link.
