Does anyone know what brand the Summit cams are?

I believe they are Crane.

Ok, thanks. Do you know if the crane cams are any good? I was thinking about getting the comp 270H cam but the summit ones are only like $95.

Who grinds them isn't as important as what the specs are.

Correct. Crane manufactures their own cams, and the Summit ones as well, Comp only manufactures about 25% of their cams. They buy a majority of thier cores from Crane. Both are very reputable, I have never had a problem with either one of them including Summit. As was stated before, pick the best profile for your application. That is what is most important when choosing between these companies.
