Can anyone tell me the exact sizes for the freeze plugs for a 1966 240cid?
I bought a brass kit from eBay and the seller listed it as fitting 1965 thru 1976 240cid, but none of them look like they’re going to fit. I need to replace the ones on the manifold side of the engine, and not one of the plugs in this kit are the same size as the ones needed for the manifold side plugs. The part he sold me is EP107BR and he is insisting this is the right kit, but this can’t possibly be right. The sizes in this kit are:
5x 1 5/8
1x 2 1/16
1x 2 3/16
Can anyone please confirm what the correct sizes should be for a 1966 240 so I can reply back to the seller and hopefully convince him to replace this set with the correct set?
