Purple plate build

its vavle timing, with the degree of the crank, something like that, get on youtube and look up ARC, Jody has a nice video that explains it and shows how to set it, you will need a few special tools, Good luck,, Im sure a engine guru will chime in soon enough!
 
Agree on the ARC video, Jody does a fantastic job explaining it to the novice.. a simple single degree off on the centerline can make a huge difference in how the cam performs. Looking back in my notes, the EV6 centerline is best at 111.5 degrees
