Hello Jeff'z 46 GMC,

You might have some luck getting that engine identified by visiting the "Inliners" website.

When you get there, click on casting #'s.

I believe there is a serial number stamped (not casted) on the block, but I'm not sure where at. I have a 228 block out in the garage. When I get a chance, I will look for the serial number location. I know on a Chevy, it's next to the distributor, on the machined pad.

Welcome to the Bolt

John
