[Mgs] Engine ID again

[Eric Markley]

Hi Tom,

This will be more difficult.

IF the carbs and distributor are the original units for the engine, the ID
numbers on these components can give you a close idea of the engine series
you have. If they are not original components, then you will have a tough
time. The series number cast into the top of the cylinder head will give you
a clue, if it is the original head for the block.

The model and series number should be stamped on the side of the
distributor. SUs should have a small metal tag attached to one of the screws
that attach the air chamber to the carb body. Try to find these and send
them out.

For example, the engine in my '74 is a 797AE from a '75, with '73 AUD 550
carbs and it had a 41369 28/71 Midget distributor installed when I bought
it.

I believe that there are casting dates on the heads; don't know about the
blocks.

Eric

First off, thanks to Eric, Phil, Max and Paul for identifying my spare
engine. Now, the engine that is in my 1974 (chrome bumper) GT does not have
the engine number tag on it. Some previous owner removed it. And I do not
know if it is the original engine. Can anyone give me clues to look for so
I can identify this engine. At one time it did have an air pump. The Timing
Chain and Sprocket are single row.

Thanks again,
  Tom
