A few people had asked me about the 030-030 camshaft that we are using in the 302s that I buiid here at the shop. I'm putting an engine together today and have the cam card. Part # is 12-107-3, CS replacement for 3849346.
Hope this helps. We have had great luck with Comp Cams. Years ago, we have a couple of issues with the Crane version of the same cam. Two wiped on us and that is a nightmare that no one wants to go through. Probably a batch of bad cores.
