For those who hate lunati, too bad. Engle and ultradyne are great cams also. Erson, I can tell you haven`t built jack shit and if you did then it was junk yard crap. And I already know you`re gonna write back and tell me of all the bad ass shit you and your ****in` buddies have built. I think before hand that you are full of shit! Erson sucks and any serious engine builder or someone willing to sacrifice quality for a quick," hey look what i`ve got, fix would not use them. And everyone I know who used a Lunati has had nothing but good things to say about them. maybe you installed the cam wrong or advanced your timing too damn much. A Lunati has four degrees advance ground in them. Go bullshit someone else bench racer! Read some more HotRod and CarCraft and tell me how much you know. Bench racers, damn.
