390 Block Identification

2001 Views 2 Replies 2 Participants Last post by  rfield
I've been looking around trying to see if there's any information available to help me identify my block and haven't had much luck. My heads are fine 68' 390 GT but the block is odd. It has the following located between the casted screw heads.


These are the only markings located under the Oil Filter. The only other item is that the block also has ribbed sides. My best guess is a service block or something out of a truck?

Would anyone have any idea what it my be?

Thanks Dreger.

That makes sense, my tranny part number is D4TP-7006-A1 and from my searching appears to be from a 1974 Pick-up/Bronco.
I also read that the mounts for truck blocks have four holes as opposed to three. I do have four.
