I spent $50 which at the time I incorrectly thought would be decent quality. Obviously I was wrong. I think I have seen you recommend the Cloyes street billet true roller before which Summit has right now for $93.00. I also think I remember a post where you referred to advancing the stock 318 cam for a little more low-end without really hurting the higher end. Not like there is much up top to lose anyway. I've tried finding the post I remember multiple times and cannot locate it.
