Can anyone tell me the size of the RB block cam freeze plug that goes into the back of block between the screw-in oil galley plugs?

My machinist and I must have had a small communication breakdown when I asked him to leave out the oil galley plugs, 'cuz I realized while washing the block that the cam plug wasn't installed, either.

It'll be easier to stop by the parts store that's 5 minutes down the road than make a trip back to the machine shop, if someone can tell me the correct dimension for the missing plug. Thanks.

I have SB cam plug here in front of me that says 1 7/8" on it. I don't have a BB here to check.

I do have 2 KB hemis sitting here that have 2 9/64" cam plugs in them. I have no idea if there the same as a iron BB.

Brad, it's 2-1/8"(the 2-9/64" will work as well). Not likely to find at any auto parts or hardware store. I prefer the more "cupped" variety over the shallower ones, but I have seen them both ways and either will work..

Thanks. I'll try to find one this weekend.

Oh, what's the recommended sealant to use when installing a freeze plug?

The last time I bought one, 2001 or so!
The parts store said they would no longer carry them and he was not sure if Dorman still made them. He had 8 in a box so I bought them all. If you do not find one this weekend send me a PM with you address and I can send you one.

I checked today. The ones I have are Dorman P65C Cup type 2 9/64 like someone above said.
