Need help on centerlining my cam.

Lars you are advanced 1 degree. 105 is 1 degree advanced from 106 degrees. You did good. Isn't it fun too. Knowing where it is, is important. Insure you have piston to valve clearance. Advancing the cam closes up clearance on the intake valve and opens up the clearance on the exhaust. retarding does the opposite. Good luck there, you do learn fast. Terry.
