What will people cry about tearing up next? What rule change will they demand? How much will it cost?


Where will it stop?

All this type of unfounded information ,that is just flat wrong again ,and again is not welcome by many ,simply put we are already using billet camshafts ground for solid lifters, that are DLC coated in order to run valve spring pressures well above the limits of a solid lifter at what is already what many say on this site as expensive , so maybe the uninformed may want to go do some of there own research as to the cost before they make false statements , I have said this before many times on this site since 1985 car manufactures have went to roller cams , and before all you opinionated racers express your own views telling others to run a car with roller lifters from the factory ,you may be better served by understanding there is a reason as to why many like running the older cars
