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

If the cam bearings are worn and you aren't going to replace them which would be the best practice, I don't think I'd put a resurfaced cam against worn bearings. Wouldn't a better practice be to line-bore the cam bearings back to a uniform surface (assuming enough babbitt is present)and spray-metallize the cam journals and finish to proper clearance? I'd think hard-chrome is probably a bit of overkill. Good topic to hear Jack Vines' advice.
