Ok so my class of mud racing changed some rules today allowing me a few more mods. I was previously only allowed to run a hydraulic flat tappet cam, headers, carb and intake. This year the class has allowed a fourth bolt on, which in my case I'm thinking should be mechanical roller lifters. So my question is will stamped steel rockers hold up to the stress of a mechanical roller cam, because roller rockers would tech me out of my class. has anyone here ran steel rockers on a mechanical roller, and for the record I am not thinking of running huge lift numbers.
