Comp Cams makes them....
The cc305 utilizes much older technology "magnum" lobes versus the cc503 which uses more recent and more aggressive "xtreme energy" lobes which is good for more power. Also, the cc305 comes standard with a 114lsa versus the cc503's 112lsa. Even the 112lsa is wide but it is beneficial over the cc305's 114lsa unless your running a real big hit of juice or have a blower etc. Also the cc503 will sound choppier since it has a tighter lobe separation. The cc305 is comparable in power to the hotcam and the clearer winner would be the cc503 which exhibites similar drivability with more hp/tq.
