kbiforce,
Well, I don't want to sound know it all-ish, but imo, running a cam advanced a total of 12 degrees is absurd. It would cause the intake closing event to occur at 30, alright, but all the other event would also more 4. Since the 204s are already advance 8, the exhaust opening would occur awfull early.

The idea is to have the intake valve close at 30 degrees of rotation. The spec on the 204 is 34 degrees. The TW21's are at 30 already. He said the sooner the intake closes the sooner the power comes on. We used the 21's on a 95 and the run real good.
