The writing on the block….
After cleaning off the engine, I found some writing on the block
I found this painted on both sides of the block. What is this? Is this the equivalent to the writing in the firewall bay of Chevy’s? BTY do GMC’s have the writing on them? I have the block numbers and I’m trying to figure out if it’s the original engine or not. 65-72 chevytoys gave me a link to help me with matching the numbers. Thanks, s/t
