What's the best method to clean these out? Can't seem to find a wire brush that will fit the bore. Maybe a scouring attachment for my dremel? Yes, I'll definitely make sure the lifters spin freely before I assemble. -Jim I can fix it... my old man is a television repairman. He's got the ultimate set of tools... I can fix it.

Might be large enough if the rust is VERY light.

Next size up is a 1" which would be a bit over size. -Jim I can fix it... my old man is a television repairman. He's got the ultimate set of tools... I can fix it. Currently Mopar-less

With a small hone you won't get even pressure... 15/16 would be ideal & they do/did make them, I have one from back in the 80's... But a 1" will work just don't do more than a couple passes with it.. Use light oil & expect to be cleaning the block again... "The Armies of our ancestors were lucky, in that they were not trailed by a second army of pencil pushers."

That said, just give them a couple passes to get rid of surface rust. Any deep pits will not affect the lifter. The last thing you want to do is make the bores bigger!

Some places jump from 7/8" to 1 1/4". It would seem to me that you'd want just a little interference to truly hone. That said, for removing rust, 7/8" is probably the way to go.

Works great to remove the rust then a light clean up with the hone.

Harbor Freight has a three stone job in stock (cheap too): http://www.harborfreight.com/1-1-8-eighth-inch-brake-cylinder-hone-97163.html -Jim I can fix it... my old man is a television repairman.

I'm not condoning it's use just saying it could be done if you are real careful. What I was trying to point out to the OP was that trying to clean a .904 bore with a .875 hone is going to be futile .

It's all moot now. The 1" steel brush from HF with a little PB Blaster cleaned the up real nice. -Jim I can fix it... my old man is a television repairman. He's got the ultimate set of tools...
