How to Order the E-4 Cam?

Scroll down to about page 122, it shows that cams part number and all the sprcs. Pretty sure no matter where you order it from, either through Summit or even directly from Isky there will likely be a delay, unless they got a batch of cores in recently. I would call ISKY to find out the status and then order it from Summit, as it will be cheaper that way, at least that’s what I’ve found when ordering a catalog grind from them.
