@Husker6.5 , yea I have spoken with them and most of the other big name cam shops with no luck..
Think of it this way, Ford, Chevy, Dodge, gas motors are very popular in all kinds of racing, small & big blocks and any mix of them, so those cams would sell...
Most of the owners of a 6.x balks at spending 200$ unless they believe it will add 200hp
That and the fact that most would ask for engine dyno proof of said improvements, I may be able to engine dyno my build next year, at the same time this is for ME, I know there are regrinds out there, and I already know a regrind is a waist of time, very little can be changed with regrinds, this motor can become better with a better cam, this was designed to be a fuel mizer period, making slight changes to a stock cam doesn't do anything real...
