New engine issues

I'd like to put in my vote with the guys questioning that Erson cam. All that duration and not much lift. I had the same cam in a 318 Challenger with power steering and air. Just a touch of stall in the converter. 600 vacuum sec. holley, headers. A real slug !!! Took the front of that thing back apart and stuck in a split pattern Crane with about 260 / 268 or so and car ran real good. Get rid of that cam !!
