Synthetic oils

Wrong, I would suggest that before making statements such as "you shouldn't need the zddp (zinc) during breakin either" you read up on the subject. The skinney on todays oils is that the zinc is being removed plain and simple. Flat tappet cams and lifters need zinc on their contact surfaces to survive especially if running dual springs.

Here's one of many articles on the subject.:read2:

wrong eh? lol ok. thanks for the link... but I don't need to read what a hack has to say. soft springs are needed for breaking in a cam. you wanna run hi-pressure springs, you take your chances. well with a mech. cam anyways. go roller if hi-spring rates and hi-lift turn you on. simple.

now before you start making YOUR statements about what is right or wrong, I promise you there's millions of flat tappet cams running around the world just fine and dandy without zddp in the oil. I guess somebody should inform them LOL>
