kbiforce,

Fyi: the SE 204s have 8 degrees of advance ground it. Surely he doesn't mean to advance them 4 more. Perhaps he means to back them up 4, so they're installed at 4 degrees of advance, rather than the "as ground" 8?

In the Tech section with Joe Minton, he says the factory cams are too big and says to run the 204's advanced 4 degrees or use the TW21's. Pretty interesting! Thought I'd pass on the info. Happy New Year and Happy Motoring!!!!![/quote]

Joe did say to use a Crane cam gear that has a 4 degree advance. 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.  Joe also said that the 103 will act the same as a 95 but will natually have more power because it's bigger.

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.
