Don't think cams are bolt-on power... they require significant tuning... ignition, fuel, and especially timing. A MAJOR tuning drawback of the FE slave gear design is cam tuning...

Is it because you can't move each seperately? I'm not real deap into the tuning world yet, I just haven't had much of option yet. It just seem like they're be too many times you'd nead to move them seperately. If you agust the timing on intake to advance it, it seems like exhaust would follow. I just want to know the reason it's so bad. If you don't reply, I'll see if I can't find the answer somewere on the net. -------------------- Live Free, Be Happy

[right][snapback]340073[/snapback][/right] Depending on the cam profile... sometimes tuning for the best power, best torque, or whatever will make better results when one cam is retarded and the other advanced. This depends on the cam profile and other tuning... but it is a great limiting factor in cam tuning. Again I'll repeat... camshafts aren't bolt-on power. If you don't tune them... they can just make the engine run bad. -------------------- "It's ok to be naked girl... I'm an artist!"
