To get a good lopping idle, most will use a CAM with a low LSA (108 - 112 deg).
But to get good HP out of it, the rest of the cam dynmaic need to match up to provide good torque and HP. The Thumpr Series cam were design with this in mind. The not only use a low LSA but increase the duration of the Exhaust to help with the power and idle sound.
Many will say to you not going to get much out of it. but then other have said you will get good power... so..depend on what your looking for. If your looking to get a mean idle while cruising. The Thurmpr well be idea. Not sure of HP / TQ.. have not really seem many report there dyno numbers on it.

Wrong thread perhaps? Anyway, looks good. I'm about to do the same spindles with c6 brakes.
As for the thumper cam, all I've ever read is people bashing it but not giving any real reason. I wanted the same stuff as you and ended up with a TR224 on 112. A pretty common cam that doesn't seem to require much special to be useful.
