im currently trying to get my evo 6 4g64/63 tuned im wondering what ur adjustable cam gears are set at on tdc 0,0....id like to know cos its not exact like a 63 at tdc and its not at 0,0 cos of the 6mm taller bloc of the 64...any help is appreciated

 

Retarded 3.75* is 0 on the valvecover marks with the bottom mark lined up.

 

is that what it should be showing on both gears???

 

Correct
