Hi,

Regarding the cam timing... both the GP2 and GP3 have 110 degree lobe 
centers, so advancing the cam by 1/2 tooth would move the intake lobe 
center to 106-ish which is where a lot of hi-po cams are.

Just a point of reference, setting the stock US spec cam to about 7 
degrees of advance (that's a whole tooth, almost) yields a very nice 
torque curve and some of the Street Prepared TR6 guys do this as a matter 
of course. It works.

Timothy - you are right, it's best to install the cam as spec's on the cam 
card. However, when you're looking for extra ponies you can get better 
low-end torque by advancing the timing a smidge.

Over and out
