Cam Install Question

But it still matters. If you change on variable in the equation, the geometry needs to be corrected, no matter what rocker you use.

That could be lift, stem height or both. If you change one thing, it undoes what Chrysler did with shaft placement.
Roger.... I wanted to point out that the 273 rocker does not work the same as a roller so not all of the B3 info is applicable.
