MG MGA - Looking at an A to buy

I'd like to make sure I'm getting an A with an A engine, even if it isn't 'matching numbers'. I've owned a B and an A 40 years ago, but I wasn't that fussy back then.

What are the differences between a '60 A engine (badged as a 1600), and a B or ?

My TD has a data plate. Do A's too?

Anything on these pics give a clue?

The engine No is stamped on a plate riveted to the top of the engine block.

Is there a handy list of engine numbers that I can compare it to?

Main difference is the mechanical tacho drive for the MGA, which I don't see (the cable) in your pictures. Engine plates are easily removed and replaced, so no guarantee.

Why not buy Clausager's book "Original MGA"? That provides all the answers to what should or shouldn't be fitted.

There are a number of cosmetic modifications in the engine compartment, but nothing that cannot be put back to original if desired. Neil has queried the apparent lack of a tacho drive. If this is the case then, more than likely, you have an 1800 engine implant from a B. A quick check of the instrument panel will likely give you another clue. If it is an 1800 you will have an electronic tachometer (Smiths). All instruments in the A should be Jaeger. One other obvious mod is the alternator.The A came with a generator. Many of us have all these modifications and a lot more.

An early MGB 3 main bearing 1800 engine will have a mechanical tach drive. If you think you may have an early B engine you can look on the left hand side of the block near the front plate. You should see a 18 cast in the block.

I just put a 3 main B engine in my '59 1500 and it makes a world of difference in handling our mountain roads in NC.

Early cars listed engine numbers on the main body plate. Later cars helpfully read "see engine".

Neil Cairns made a list of all BMC engine numbers and the cars that they were used in.

A 1500 engine from an MG Magnette doesn't have the tachometer drive, nor will a transplant from other contemporary BMC cars. They will have different engine number prefixes though.

There are plenty of honest reasons for an engine swap on a 60 year old car.

Why not post the number here ?
