If you are looking for a complete rebuild kit, it will have to be specifically for a small journal ('62-'67) 327. Of course you can also just purchase the necessary parts individually. The only things that are specific to the sj will of course be the bearings, front and rear seal, and rod bolts. There are a few other odds and ends, but mostly if you are looking to do a original restoration.

The rpm range for any engine whether small journal, medium journal or large journal, is going to be dependant on how the engine is built.

As for the durability of the Summit brand cams, they should not be any less durable than any other flat tappet cam. The main concern with any flat tappet cam is that strict attention is paid to the breakin of the cam, as well as running an oil that has sufficient ZDDP for a flat tappet cam to survive. Keep in mind that the Summit brand of cams are all old school designs, and that there are better cams out there.
