My 422 smallblock build

I remember with my old cam my best friend went for a drive with me and at first he didn't think we were going to make it home the car was running so bad but then when I opened it up he was holding on for dear life and when we got back home he had a big smile...
Again ran like crap under 3K but that was my experience it sounds like you're having a much better one...
When you ran your old big duration cam did you happen to pull a compression test?
Is so, what kind of cylinder pressures did you see at cranking speed?
