According to my father I was born not willing to believe what people told me.
So its natural that I have never believed a lot of the gospel about Volvo engines and most of the time this as proved to be a good thing. I usually have to see it to believe it.

Part of the reason for asking this question in the first place is the following
email I received recently from Europe:

Hi
Yes the walls in 75-76 b20 is thiker they are from the 240 series only 75/76 whid M45 gear. Im not sure how thik my walls are. Did just bought that engine from a sweed . But they are 93,98 bore. I got 2* 75/76 mod b20 one hevyely modified and one std engine.Her we say thay not biger bore than 93 on 72-74 block an 92,5 on earlier block
75-76 block 94mm

Of the 5 blocks tested recently, 2 being 8 bolts, the one with the thickest walls would have had a spot high on the thrust side only .935 thick with 92.5 bore.

Shayne, I don't have your block specs handy, but am guessing that it would have been pretty thin with a 94 mm bore.
