It looks to me like they shot peened the block.

It is six.

Glad to hear that because 4745 is a 427/400. It was on ebay a couple of months ago. The numbers look pretty good to me. Is it a 4 bolt main?

Since you own the car you can give Al Grenning a call and he may be able to affirm the stamp with his data base.It is money well spent as his blessing (or not), kinda ends the story...Otherwise in the end the free advise you get will leave you still wondering... by the way it looks good to me...

Yep, it's a straight back "6" and there should be NO 4 bolt main 400HP 351 blocks out there. They were all suppose to be 2 bolt mains.

Same casting but machined differently.

Re: 67 Stamp pad opinions

Well considering that there is absolutely NO broach marks on the deck of that block I would start asking every expert that I could find.

There are several blocks that have thru weather, rust etc. lost the broach marks on the pad BUT I have never seen one loose the broach marks under the head!

That's a flag going up in my opinion.

Re: 67 Stamp pad opinions

Just my 2 cents, but I just OJ'd at the Nationals and did mechanical on 8 of the 16 1967 Vettes there and we had a similar stamp to the one you posted. One thought the Judges had was they'd like to see the bottom of the "J" come up a little more, and be a little longer than what you have pictured. I am not an expert, but have looked at a lot of stamps and that is one thing a judge may find with your stamp. Just my thoughts. ARA
