Most cams end up with wiped off lobes and hollowed lifter bottoms today because there are no additives in most of the oil for flat tappet cams. There really have not been any flat tappet cams used in modern engines for the past 20 years or so. Give or take a few years for some possible hold outs. The point is every new type of vehicle has a Roller Cam or Overhead Cam these days.

You have to add an additive like Comp Cams part number 159 Cam Break in Lube and we use a lot of Joe Gibbs XP5 Race Oil. We have not had any cam problems since we started using these products in all our Performance and Race Engines. The Comp Cams additive is only $10.00 and the Joe Gibbs XP5 is about $10.99 a Qt. It is a Semi-Synthetic 20-50 Blend. It cost more but you can run it much longer. Most guys run it through 3 oil changes and only change the filter and add a qt. I sell a lot of it to almost all the racers. Cheap protection against camshaft failure. Of course don't forget to properly set the spring pressure and valve lash too. Oil can't fix everything and there are a lot of guys out there working on engines who should have never picked up a tool.. they make it hard for others who come along and buy a project not knowing it was poorly assembled. Let me know if I can offer any help. Mike at, mikesspeedparts@aol.com
