SB 360. I have some Dorman 1&5/8" & they practically fall into the block openings & the freeze plug OD is a bit wavy. I did grab one dorman 41/64 which is a hair larger just to see if it would fit & if so then I would get more of that size IF they are available in a thick (wide) version (like the 1&5/8's are that do not fit). is there a better brand that fits tighter? I could go brass if they tend to be tighter. thank you for your time.

the deep 1&5/8 ones are 9/16 "tall" & the 1&11/64 one that fits better but is only a weak 3/8" tall.

yes the block hole(s) & the Dorman plugs are 1&5/8 but it is way too loose. I'm gonna try a brass one I have & if no go then see if I can find the Sealed Power 1&5/8's you mentioned.

My brass one fits alot tighter (& probably a good idea to use brass anyhow especially on the (2) rear plugs). it says 1635C with no brand. I Googled it as a sealed power # but nothing come up, anyone know what brand it might be?

Good info & I may very have had one of their slightly undersize ones (I didn't retrieve a # or take a pic like I should of) but it did about fall into the bore. Now that you mention it I did try a 1&41/64 & it was a tight fit just setting it up to the bore & I was worried that I might crack something if I drove it in & it was steel & haveing always used steel & everyone touting brass I decided to go with brass (at least on the 2 rear hidden ones). I certainly was not expecting the amt of difficulty I had on this simple issue.

The Dorman's I just received (made in China) are obviously now chamferred so they seem loose and go in half-way by hand. It seems to be a manufacturing modification to help us get them started in the hole easier. I don't believe they are defective or too large.

Interesting, I replaced the freeze plugs in a '77 318 and a '68 383 last summer and simply asked for the kit for those motors at Orielys and thought nothing of it. They fit perfect. Still no idea what brand they are. I really should start taking notes. I've never needed sealant with freeze plugs.
I have mechanical Aptitude. I can screw up anything.
