To Much Cam?

Its 28 initial and 6 mech. I way I acheived this was installing the 18* bushing in my msd dist. and I tacked a weld to the side of where bushing stops a full mech advance on the distributor. I know its barbaric but sometimes you have to get creative! I guess another way to do it would be to find something that is the same diameter as the 18* bushing and offset drill the hole.
