Re: My Jesel Saga

Chris,

On the midlift theory, I don't disagree with the approach/theory of 90º at .5 lift at all. It makes good sense, but then again so does having the max mechanical advantage where the spring pressures are the highest. I have found similar misalignment (front to rear) on my AFRs with the Jesel rockers as well. The 516060 parts reduce the misalighnment a LOT and make it tolerable (with the 506060 rockers, I would have had the arm dragging across the valve tip before long.)See the not to scale diagram. That is why, with all things considered, if I can get the orthogonal point somewhere between 1/2 lift and 3/4 lift, I'll be doing good. To be able to more precisely control the path of the roller across the valve tip is, apparently, cost prohibitive for me. So, as is not uncommon, I will have to settle for a compromise. I hate having to compromise, but the wallet is just so deep.

I am shocked by the cam variation. Is this just error in the lobe locations on the cam? And, whose cam it is? I would have never even thought that the cam would be off like that! At least, with one that's not from Joe's custom cams in downtown Podunk. And, I can't imagine that you are not using a quality cam.
