just got my block back from the machine shop

[felix37]

I just got my block back a few weeks ago and have been taking my time prepping and cleaning my block and checking and adjusting my floating bearings as per Ol ron's book. my question is, the machine shop removed my main studs when boring my block. what should I torque them to? I imagine it shouldn't be much as they will be torqued when the crank and caps are installed. also, as I have been using my micrometer checking and re checking all of my bearing clearances I have left minute fine scratches on some of my bearing surfaces as well as on the bearings. should I be worried about these or should I polish them out with a very fine wet/dry paper,800 to 1000 grit?
any advice from you engine builders would be greatly appreciated!

Use scotchbrite & solvent to polish your bears , the marks from measuring wont hurt a thing . but for 45 years I scotchbrite all my bearings & thats in high $ chev & Ford race engines also!!

NO ! Never use wet/dry sand paper on the bearings.
There was a post on bearing here on the ford barn. Some of which I don't agree with, some I did. You have to decide for your self.
The bearing have a coating on them. I use a clean, fine towel to wipe the coating off. This will probably clean and scratches you have on them.
Take the time on go back to the lenghty post regarding bearings. A gentleman "GM" worked for Federal Mogal, and has great knowledge about bearings.
NO SAND PAPER !!!!!

I use a scuff pad to clean up the bearings and wash them is soapy water. The scuf pad leaves a nice surface for oil to adhere to.

Ol' Ron:

Your not saying fine steel wool are ( I don't think so But!!!!! )

NO TORQUE. They should screw in by hand and leave them a 1/4 turn up from the bottom.

Bill, steel wool, sandpaper, sandblast, anything potentially harder than engine surfaces, should never be used because you never get it all out. I think Ron's "scuff pad" is generic for Tony's "Scotchbrite".

KiWinUS and Ron, Are you talking about the red 3M scotchbrite pads or the finer grey ones?
Pete, thanks for the advice on the main studs!
