I've found a block with the following specs:

- 7 Rib block
- 40mm crankshaft
- no extra-meat
- 10:1 pistons w/o the sublevel

What may be the origin of this block? Seems that its mixed up and it's a transition block....

Revive the Ancient thread! I'd love to see those pictures, that are no longer hosted. I believe I have the same engine in an American AE92.

Not likely... but in 30 (+ or -) years just about anything is possible

have you opened up your engine yet? look at the pistons..... take a photo, and share it with us.........

You can |Sad .... OR you can ask for help!!!

I'm sure it's original equipment. The car has 199k miles, I haven't cracked it open yet. I have rebuilt the distributor, and fixed some other oil leaks. The most I've done is the valve cover gaskets. This weekend I'm thinking about doing the front crank seal, and my original concern was if there were variations in crank seal diameters between bigport generations. I guess I'll find out tomorrow or Monday. Or I might wait until I have the belt and water pump. Thanks for the reply. If I find anything odd I'll put it up here.
