The 383 is apart for a refresh. The cam is a Crane HMV 278-2, 222/234 @50, 467/494 lift, 114 LSA. I measured the cam lobes looking for variance, and I found it. The exhaust valves range from 1.591 to 1.598. The intakes range from 1.571 to 1.580, except one lobe that is 1.543. That is .030" smaller than the average. I am reluctant to re use this cam.
