Engine Date ?

[427FE]

Ok so ..........

How do you prove to the MOT'er that the engine is pre 72 (or 75 is it?) for a visual emissions test ?

Do you produce a receipt showing this ?

Or documentation of the engine casting numbers with stuff to back it up ?

Also regarding SVA Test what do they need to know the engines age ?

Regards

Engine casting codes is the usual way. Yes, SVA will want to know the engine age as they do an emissions test as part of their scope.

With a forum name like "427FE", I assume a ford engine will figure in your build?

Ford casting codes are deciphered in the usual "How to rebuild your Ford Small/Big Block engines" books by Tom Munroe (nice guy btw).

I'm a little rusty, but if I recall correctly, the first letter denotes the decade i.e. "C" for the 60's, "D" for the 70's etc. and the following number denotes the year in that particular decade i.e. C7 would be 1967.
The following letters identify what it actually is, unfortunately, there isn't an easy method to decipher them. I seem to recall that C7AE is a hydraulic 427 side-oiler engine block. Some parts will then have another letter after the main group of 4, seperated by a hyphen. This denotes the revision of the casting.
Therefore, it should be very easy to prove the year of your engine, unless you're trying to prove it is something that it isn't

I hope that helps.

Thanks for the replies, I know mostly how all the casting numbers work, that includes the date code and the DIF foundry code for the foundry the 427 60's block was cast at.

The ford date code for these (and many other blocks of this era) is in the form of 3A12 which would mean Jan 12 1963, 6E23 would be May 23 1966 etc Most FE blocks would also have the code 352 in the casting at the front of the block. Next to the DIF (Dearbourn Iron Foundry) would be a number this being the mold number the block was cast from. The 427 had C numbers ranging from C3 through to C8 ie C6AE-B and these numbers designated things like Year, Top Oiler, Side Oiler, Irrigation, Marine, hydraulic lifters etc.

I just wondered how the SVA or MOT'er worked this out, ie if they know all about the casting codes or do i have to have it documented with some sort of proof.

And yes i will be using a 427 FE engine Side Oiler 1966 block, but getting hold of a good one of these is difficult.

you will need proof for SVA, any of the well known books or manuals will do.

I've just ordered an 427 Side Oiler from Southern Automotive. Bill was very helpful and knowledgable. They're not a cheap engine, but there are plenty available. There are even some NOS blocks available. I know that both SA and Keith Craft have some. And then there are the new Genesis and Pond blocks, both of which, I believe, have the original casting numbers on them.

Dave,
A lot of the early Ford blocks didn't have an engine number. Even on a tag.
You may have to stamp your own number on it and use various books, a certificate from the engine builder and the casting number to prove the age. This is what I am doing with mine.

Out of interest, what kit are you planning on buying?

Pond blocks do not have all the correct codes on them only C5AE H and the 352 casting code, the CS blocks have no codes on them other than the CS Signature, Genesis i believe have the C code and date code. Although these are not genuine 1960's 427 Blocks.

I realise that also, but most 65-67 engines had numbers on them.

Kit Car........

Going to visit Dax next week, also looking at GD and Hawk. Not sure yet till we have seen them all, Dax is top of list so far. (Was also pointed towards Madgewick in Pagham which is a stones throw from me, although i am not impressed with there web site and there is no mention of using a 427FE engine in their kits)
