What they said, also looks like the oil pick-up tube bolts on at a slightly different angel ?, oh yea, ones is clean and painted.
So?, do we get a free T shirt?

looks like a pretty big difference in the casting at the right-hand rear of the block where it meets the bellhousing, but yeah buggered if I could find 6 differences?

Thats what I was going to say!
I give up, you tell me?

the one on the right has no camsharft either

C'mon D, put us out of our misery before this gets pushed off the recent pics page.

I had an A14 and A15 block, both stripped bare sitting on a bench at work today and could only really see a few small casting differences, nothing too obvious though. I doubt there would be six major differences between the two.

I have one of each at the workshop. Next time I'm over there, I'll take a picture with a tapemeasure across the pan rails. (If I remember! lol)

Thanks. Look forward to measurements. I expect the outside of rails is same, but inside is a couple mm different. If that's all the difference is, one could easily modify the A14 block with a grinder to match. More important is the oil pump pickup location being moved.

I'm not entirely convinced that the pickup has been moved. It's not really possible to tell from these two pictures, but by placing a bolt in the first & third pan rail bolt holes & running a string between them a better idea of the juxtaposition between the oil pickup mounting points & the pan rail can be determined.

A few measurements from hole to hole will also reveal the truth.
