If your using Adjustable Cam Gears, that means they have adjustment.. where were they initially set?.. Typically if you have Decked heads or block, the Drivers Bank will be off less then the passenger bank ( Number of Parting Lines that were Shaved, the belt must Cross is Less on the Drivers Side then the Passenger Side .. so the Difference is less on the Drivers Side )
I'm thinking the Gears just needed to be set.. that is what you do with adjustable Cam Gears..
