Hello from ia

when was the last time you rebuilt an engine? not trying to be an ***, but I've seen countless videos all over the internet with cams going out on break in and not just your backyard builder actual engine builders. yeah ik that people that don't have issues don't talk about it as much as the people with. but it still worry's me.
No problem. I do not think you are at all being an ***. The last engine I did was a small block chevy about a year ago with a friend. It runs great. Those old SBCs practically fall together by themselves. I hope I did not come off as an ***. I was just trying to show you that there are millions of engines out there with flat tappets that did not experience problems on initial startup. I use a liberal amount of Royal Purple assembly lube on everything when I assemble a motor. Now there may be something to be said for camshaft quality not being what it used to be. That is why I stick with Comp. I have never had a problem with them. There is no question that rollers are better.
