I prefer to use a specially designed plate we have made here and then have heat treated.
No worries here with that deal at least till 9-10,000 rpm.
As cliff will agree , almost any center cam that is used with a super light set of springs will allow extra advance, even mine, but I don't like light springs anyway.
They're not needed if you got the right parts to begin with.
If you want 100% dependability that you can stake your life on, then a mechanical stop should be in your future, whether you weld it, epoxy it, screw it, or whatever.
There is cut and try with all of it, you just have to deal with it as such. I dislike the mechanical means on a circletrack car for a couple of various reasons but there are ways around that deal although nothing too cumbersome if implemented.
Still for what I do here the properly shaped/engineered center cam is the way we do it here, the folks over at Performance Distributors are in complete agreement on this also.
I never proclaimed anything.
