Interested to see what some of the knowledgeable people on this forum think.
I have seen them in circle track engines and a few of those guys around here swear by them, but have never used one personally. I have always preferred to put the time into balancing out the intake flow with the carbides and testing. In theory, it makes some sense; but I am looking to see if anyone actually has any first hand experience with them.
So, are 4 pattern cams just Black Magic/ snake
oil or are they legit and based on sound testing?
