I think being able to get all 12 rockers to have the same ratio would be a huge benefit in and of itself. Even the actual error in ratio and consistency in a stock set of 12 is going to make it worth doing. I can CNC a set of either the Chevies or GMC relatively easy, with a minimum of fixturing. Just buying the roller tips and pins and adjusters is the main expense. If Ron has a drawing of what he has in mind for the GMC's, its pretty much a slam dunk as far as me making a set to help out the cause....
