NWell, I am not running a solid roller, I am running a hydraulic roller. It's a custom grind Kam Motion stick, that Ron Robart at
Fox Lake Power Products scienced out to match my heads and what I wanted to do. I'll never find the true potential of the engine I have probably, as I can only spin it to 6500 RPM... But, I wanted a low maintenance, sturdy, not going to break it engine. I had enough of that in my push it to the limits 302 days...
Regardless, the cam I have is backwards from what you might think. It is around .600" lift on the intake side with a 1.7 rocker and around .575" lift on the exhaust side. Yes, it has more on the intake than the exhaust. The duration is as expected, however, being around 228 on the intake and 236 on the exhaust. All this is on a 114 lobe. Actually a conservative cam for this big of an engine.
When you're making over 550 HP or so, you will actually make more power by having the intake have more lift than the exhaust. It's backwards from a lower HP engine.
