Please help engine identification

What’s the engine number stamped on it

Thanks for any help already

Those heads are Oval Port Heads.  Not D Port Heads.  Not "Special" heads. Stock standard regular heads.

OK, not sure where your finding the AA and AB references from but here's the section for Engines from the Australian Capri parts manual. Have a look through this to see if you can identify all your bits and pieces.

I do appreciate any help from you all, I have done some research, not really able to make sense of it all. No help from my father he either doesn't know or doesn't care. And as for his phone...,.he's probably picked it up from kmart, can't open any files you have all posted. I'll look over it all tomorrow night when I'm back home with mum.

With regard to your engine number and the other characters on the block (your earlier photo above refers), here's a breakdown of the other characters, ie. 11J22. Firstly, it looks to me like the 1 has been double stamped (like the last 3 codes of 40P on the engine number) and so the code should probably read 1J22. This is the date of the engine, where 1=the year built, 1971, the J=the month, Oct (as in A=Jan, B=Feb, C=Mar, etc.) and 22 is the date built, 22nd. So, this motor was built on 22nd October, 1971. Hope that helps you.

Yes it is, though I know of a couple with higher numbers! That doesn't mean that much though, as they can and were released out of sequence order, especially over the last 4-5 months of Australian assembly.
