Thank you Gus. I looked up Howards Cams. They look good. I was reading their reviews on FB. I found a lot of positive reviews but also found 3 people that said the lifters failed and destroyed the engine. Then I started researching Crane Cams and Comp Cams. I couldn't find reviews on Crane Cams but a lot of reviews on Comp Cams. I found more than 3 people who said the lifter broke and destroyed the engine. They might be the same failure rate assuming Comp sells more cams than Howards. Now I am second thinking this roller cam idea. I mean I really like the idea of a roller cam but I don't have deep pockets. If the lifters fail I just can't justify spending another $5K to fix this engine again. My Dodge Avenger has 170K miles on it and the lifters are still good. Why can't these aftermarket companies make a lifter that lasts. Or are the production numbers so high that the failure rate is minimal? This sucks. Is it really worth the risk and expense to go with a roller cam?
