Looking at a '65 which seems not to have an original engine. The pad where the hand stamped number should be located on the passenger side front block has no stamp pad. I need help on how to identify this engine. Present owner has no clue.

First, we need the engine block part number and casting date from off the top rear of the block where it mates to the bellhousing. The casting date in on the passenger side, and the part number is on the driver's side.

Is the stamp pad completely missing, or is the pad itself blank? A missing pad is unusual while a clean pad is not. I've seen pads removed and the external sand casting marks polished off custom engines while in California back in the 70's. The entire engine has a polished metal appearance especially if paint candy apple red. On the other hand if the pad is blank, more than likely the engine block has been decked to reduce the deck clearance to zero (stock is 0.025").

Some service blocks in the came with a short pad vs the normal pad found on complete engines. Casting numbers would tell what year and possibly application. I don't think fitted blocks were stamped at all, it was 8 pistons and a block only.

can you get close up pics and post them on c1-2?

Those guys can decipher it in minutes and tell you if its a restamp, orig or??? pretty vast amounts of know how there. Plus you can listen to everyone argue about # matching values LOL.

If owner or you arent sure dont may # matching price unless you get into the whole NCRS insanity not worth it.

The OP and I resolved this matter about a week ago off-line because he had to share some data such as the VIN number to allow the process to go on. The block in question is period correct 327 two-bolt main small journal with a casting date consistent with the approximate build date associated with the VIN.

Unfortunately, the block was decked some time in its past so the original pad stampings for both engine type and VIN are gone. They may be salvageable by a professional application of a weak nitrite acid solution or etching gel; however, the current owner did not agree to this approach.

The tach-drive distributor, intake manifold, and carburetor are all aftermarket pieces so nothing could be gleaned from them. So that's where we left it.
