To compare duration numbers between hydraulic and solid lifter cams,the generally accepted rule is to add ten degrees to a hydraulic to have a comparable solid. So you basically have the same exhaust duration,more intake duration. I would expect the solid to pull much stronger above maybe 5500 rpm due to the nature of hydraulic lifters. The larger intake lobe should raise the peaks a little,and the tighter lsa will build torque much better through the middle. I would not expect huge gains,but they definitely should be there. Keith
