Comp grinds 4* advance into alot of thier cams. Your cam with the gears 0,s lined up measuring a 106 intake centerline is indeed 4* advanced.

If the cam wasnt ground advanced and your timing gears 0,s lined up with a 110 intake cemterline would be Straight up.

The term Straight can be confusing. Its more then just lining up the dots or the 0,s of the gears.

Its the cam being installed dead center between the intake and exhaust lobes at the pistons TDC between the exhaust and intake stroke. With a 110 lobe sep cam In cam degrees if centered at the pistons TDC it will be 55* away from exhaust lobe peak and 55* away from intake lobe peak. So this cam would be centered and considered Straight up by All the cam manufactures.

And because the crank turns double of the cam, 55 cam* equals 110 crank* So a 110 LS cam will centerline if Centered at 110 crank ATDC Putting it at 106* intake centerline would be 4* advanced.

If none of the above makes sence dont worry about it. You are indeed 4* advanced now at 106* mike
