Engine ID number decoding?
A friend of mine at work has sent me the following asking if I know anything about it. I don't, but thought maybe someone here would. Thanks
The number begins "D00FI..." I can't remember the rest at this moment.
I just remembered that I needed to find out what it was. Anyway, the "D00"
is in a larger stamp than the remainder of the number. I have never seen an
id like this so it has me wondering. Any help is appreciated.

Sorry, it is a Chevrolet. It is a 327, but not sure the year.

That number looks like the start to a partial Engine Code, here is how a true stock block engine code would look:
example: T0414DM
T = Tonawanda, New York (plant where manufacturered)
04 = April (assy month)(57-59 models had either 1 or 2 digits for the month, however, starting in '60, they went to 2 digits for all)
14 = 14th (assy day)
DM = actual engine suffix (in this case, it shows this engine was a 283 paired with a Powerglide trans, a/c, 4 bbl, 230 hp)
I do not, nor can I find any reference to the characters you have listed. Can he find an actual casting number on the block?? (all numbers)Later - Craig

Get the number off the back of the block , located on the drivers side rear.
( Which is the bare block casting # )
AND the number / suffix off the front , located on the flat pad in front of the passenger side head. ( which actually determines what the engine really became )Last edited by JEFFTATE; 11-20-2006 at 01:33 PM.

GM skipped zero's and O's in engine code sequences, for fear of confusing the two. The common spots to find #s are:
1. The right front pad of the cylinder deck (above the water pump port). These normally die on the first visit to a machine shop.
2. The block casting #s on the driver's side rear, TOP (to the left of where the distributor hole is, looking forward)
3. The cast # of a block- i,e; a "010" block, which is the high-nickle block. This alone will NOT ID a block's CID.
post your #s and I can use my Hollander to find it.
