This scenario is nothing new. Flat tappet cams are a risk nowadays across all brands because the quality left the building years maybe decades ago. Unfortunately a conversion to roller is the only sure way to avoid this but mopars are $$$$$$$$$$$$$$ to convert. I see for my future project Im looking at $1300 for roller cam lifters push rods adj rocker arms springs etc. I remember on this board around the year 2000 when the high failure rate of FT cams would come up. Someone pointed out the reduced zinc and sulfur of our beloved oils. A short time later a member posted his new lifters and the LACK of a crown on the bottom. Then as years rolled on we learned about metal hardness (lack of) being an issue. I miss the days of low risk low cost high performance flat tappet cam kits.


Keep old mopars alive.
