Re: housing bore for main bearings on 7th series 8

Turn the block upsidedown. Place a lite coat of engine oil on each bearing and the crank main journals. Place crank in block WITHOUT caps.
Inspect each bearing-to-crank fit by eye to see if the crank is setting all of the way down into the bearings.

SLOWLY and cautously at first try to turn the crank. Does it turn freely????

Next, use some PLASTIGAUGE (it's CHEAP and effective).

Follow generaly accepted Plastigauge procedures/instructions which are available probably by googling "Plastigauge" or reading just about any service manual.
