All of those cams are superior to the LT4 hot cam. Are you running stock unported heads? The CC305 is just a little bigger than the hot cam. Specs on the hotcam are
218/228 0.525/0.525 lift @ 0.05 inch lift w/ 1.6/1 rockers.

I would run a cam with a little more exhaust duration like a 224/236 or a 210/224. both of them have done excellent on stock heads and even hits 12s

I ran a cam only car for two years. The cam is a lunati hyd roller. 222/232 .471/.502 112 lobe sep. The car went 12.20 with stock trans. and 11.80 with a turbo 400 w/trans brake. I know the car had more in it because the 11.80 pass was at 2700 DA. There was still some tuning room also. I think the car could have went into the 11.50's Very streetable and still has a good sound. The only thing is I don't think it would pass emissions.
