just got a replacement for my moggy, which is going to be rebuilt (the engine, not the car). its a gold seal, which i know means nothing, except its gold. it could of been driven very hard since it was rebuilt. anyway, the question is :

at the end of the engine number it has AH, using logic, does this mean its from an Austin healey? or just sheer coincidence?

'A' series engines were prefixed 8G,- 803cc, 848cc, 948cc, 1098cc, 1275cc.
'B' series were prefixed 84G,- 1200cc, 1489cc, 1588cc, 1622cc, 1798cc.
'C' series were prefixed 86G,- 2693cc, 2912cc.

The code after was to do with rebore/regrind sizes and a job number.

logical, very logical. so using that, does the AH refer to the job number etc?

Yes, thats it exactly.
AH on an original engine number would refer to Automatic & High Compression, but on a rebore it is just the job code.

I have a spare 1100 engine w/tag # 28G124R22283, After that, slightly raised, is a 2 with an S below it.
Can anyone decipher these numbers?
