MG MGA - Engine Number Guru's ?

On the paperwork with an MGA I've just purchased it quotes an engine number of:


The block itself has no tag attached, so perhaps the two don't match.

1600 is cast into the block behind the engine mount.

From here this looks like a Riley block perhaps but I don

Hanomag F35 or even early Nissan/Datsun?

Almost certainly a rebuilt engine - possibly by Oselli.

Pictures of the block would help identify it.

Many thanks Chris.

Would this mean Oselli may have retained the original engine number on their records?

I don't follow what Willem said.

Hanomag used Mowog engines. Very early datsuns are a b series built under licence fom bmc

Hi Chris,

Oselli say RK3499 is not their engine number

Any other ideas ?

Mark Hester

Could be an old XRN engine - now built by CMES (Classic & Modern Engine Services)

Where has the car spent its recent years? If you Google RK engine rebuilders you come up with German and US companies.

Just a thought.

Sounds like an MGA 1588 but the oiriginal serial number has been lost. Not uncommon when they tank them.

You won't see the 1588 engine in any of the other Austin cars, just the MGA. A '15' head is normal. The large chamber head to suit flat top pistons didn't come out until the 1622 engine in the MGA and even some of them were stamped '15'.
