Cam design limitations

Call Oregon. They did some pretty tricky grinding on mine. I had picked out a grind similar to what you want.......but it was for an Isuzu diesel and was a roller grind. They called me back and said they could do it, but it would be pointless because it would need to be a roller grind or a mushroom grind. I ended up with like .493 lift and 230 @.050. But they were able to grind it on 105 LSA from the factory 109 and it's not even close to the cam core on the base circle.
