2TG cam specs
Sun, 28 December 2003 05:57
Cam someone give me a run down on what the numbers mean on the cams in the 2TG motor.
I'm slightly confused now after recieving a 2TG head that in theory had the cams around the wrong way (printed 1 and 2 respectivly) but the lobes said that it was right.
Cheers

thanks for the offer Jason,
But I'm after cam specs more,
I cleaned up the cams and found other numbers that make more sence to me.
So can anyone give me a run done on the cam specs of 2TG motors?
