I just I stalled a cc502 cam, headers, intake, 1.6 roller rockers, ls7 lifters, and optispark. I broke the cam is amd is started running pretty bad. I checked the connections on all the plud wires, vacuum lines, o2 sensors, and checked the intake manifold for leaks.. any idea what it could be. The car doesn't have the power it should. After about 2k it picks up a little. Thanks in advance.
