there is a 1963 block on ebay ITEM # ( 150141972415 )Is the casting date correct stamping C 1 3 ???? as far as the position of the # 1 or was a # grornd away next to the 1 ? I thought if the block was cast with a single digit it was cast in the center of the month and year .......need other pictures to clear matters THANKS............

Re: casting dates
Nancy, I saved the picture and zoomed as close as I could and it looks OK to me.
It's a 300hp block. I'm not sure why anyone would grind a number off? All it would do is change it from the 11th through 19th to the 1st. Too much effort for little to no gain.
Here is the link to make it easy for others to look.

Re: casting dates
Looks right to me... The year date code is the last in the sequence and this one abutts the sand cast's insert (adjacent to the screw head). The fact that there's room between the year code and the day of month code simply says the insert had provision for one or two digit day codes and there's only a single digit day code present...Comment

Re: casting dates
Nancy, tried taking a picture but there is no room to get the camera in there.
Saying that, after reading my own scribble, it's actually a 5 not a 6. The way it is cast is (D 5 3). On mine the large space is between the D and the 5. The 5 is close to the 3.
Ten days between the cast and the engine build.
Cheers

Re: casting dates
So now we have a block cast of ( C1 3 ) & ( D 53 ) which makes no sense the 1 is close to the C & the 5 is close to the 3 ?????????????????Comment

Re: casting dates
Nancy, this was a metal foundry where guys were pouring hot liquid steel into molds didn't care if the one digit date, like a 1 or a 5, was in the ones position or the tens position. All they were told to do is get a date on the block.Comment

Re: casting dates
Nancy, The block looks good. Doesn't appear to be a restamp. Doesn't appear to have the 6 ground away. After all it's a Flint block. I don't think that Flints ever used a 6 for 63. I can see your point Nancy. You are thinking there is enough room besides the one and the other number for a 6. I think that this block would fly as far as the casting date goes. I bet if you found a casting date with a C2 it would be the same set up as far as spacing goes. So you would have room for a 21, etc. Highly unlikely this is a fake block. Looks like real deal for sure. JohnComment

Re: casting dates
Nancy, What you just said DOES make senses. I mean what difference would it make if the 5 is close to the 3 or the C. Wouldn't matter at all. Think about it. I mean the foundry person didn't have to leave room for a 51 or 52, etc but he did have to make room for a 15 or a 25th day.
So what it comes down to is that you are implying that the C1 3 block has been massaged because of the spacing. Nancy I agree with the others that the block is original and does not appear to have been tampered with. After all it is only an RD block.(low HP) Not an RF block. (FI) If I were in your shoes I would feel quite comfortable with the situation. By the way we keep forgetting one major thing. The block is a Flint block and not a Tonawanda block. The "T" blocks from the steel Chevy's would have said C63 and would have had a pad that was stamped T instead of F. And next to the big rib in front of the block the Flint block has the 1/8" pipe plug in it and the T block does not.
Also the "T" block has a big T cast into it on the back side near the casting number. So this block on ebay is the real deal.
SO with all that info I would go for it in a heartbeat. If you buy the block and are still uncomfortable with the situation that go and take the block to a police lab and have them check it out to see if it has been tampered with. Good luck. JDComment

Re: casting dates
SO it it fair to say a cast dated of say C1 3 C2 3 C3 3 could be on the left closet to the C & C 43 C 53 C 63 C 73 C 83 C 93 could be closet to the 3 ................DO you under stand what i"am tring to say .I know all about tonawanda blocks . I know the difference between a Flint block & Tonawanda block ...................THANKSComment

Re: casting dates
The pitting looks uniform between the 1 and the 3. I'm not sure how you would recreate the pitting if you ground down a number.Comment
