Engine tag info
So the Merc 410 4V I've got has this stamped on the metal ID tag:
410 67 3 Ford
7 A 330 A
I know the 410 is the CID and 67 is the year of production. Beyond that, I really don't understand the rest of it and the signifigance of it (most of my motor experience is w/AMC and Mopar). Help would definitely be appreciated so I can have a better understanding of what I've got and what limitations may be in this casting; i.e. with a Mopar the casting info is on the block-displacement,date of production, and-most importantly- the casting core number(the lower the better, starting w/#1). Also, I have seen people write about a reverse # 105 block and don't know the real importance behind that,either.

The reverse 105 block was a 70's block produced at the Michigan casting center. The earlier "352" blocks (this was found on the front of the driver's side cylinder block where the 105 is) were cast at the Dearborn foundry or the Cleveland Foundry (not 100% on this). Some 105 blocks had thicker cylinder walls, some didn't, same goes for the earlier "352" blocks. There is a date code cast just above the oil filter adapter pad on FE blocks. It's a number/letter/number(s) combo. First number is the year of the decade it was made, the letter is the month code, starts with "A" for January, thru "M" for December(skipping the letter "I") last number or numbers is the day of the month. The decade it was cast is determined by the first two characters of the casting or engineering number, which are not always present on some FE blocks.But if the first number of the date code is 1 thru 4, and it has 2 motor mount bolt holes per side, it's an early 60's casting. If there's 4 holes per side, it's a 70's casting. Production ended in about 1976, so if this first number is 7-9, it's a late 60's block.

Might help a bit.
*edit to add I don't see a 330 engine code for the 410 there. Or a 410 even listed. Kinda weird?

Even stranger is the first 410 I bought out of a 60's Merc turned out to be a 428 when I pulled it apart. Had 410 on the aircleaner lid and all indications that it was the original engine in the car, but it wasn't a 410.

That interchange was helpful, but also raised a few question for me. Where the plant code goes, I have nothing. My change level is 3- what is a change level? No 330 engine code, but the 410 indicates a 428. The final character on the second line is a letter on my tag, not a number... this deal would get even sweeter if it is discovered to be a 428!

Right there was not always a plant code and a day of production. The tag off my 68 Cougar's 390 has the same format as yours as far as info. No plant code or DOP but everything else. I'll try to find out why the 410 has no engine code listed anywhere. Probably lack of good info and resources would be my guess. Per your tag info the year of production is 67 and month is A for Jan.

Yeah, I'll have to do that shortly because it'll be going to the machine shop. Not much will be happening w/ it right off the bat because last night some tweaker broke into our job shack, cut open the job boxes and stole all of my plumbing tools (not to mention my co-workers). My project manager had us list what we got stolen and has taken them (the lists) to the office to see if insurance will cover the loses. The T-drill that got nabbed retails for $6K, so while I am out about $600-700, it could have been worse.
