383 rebuild - kinda whimpy on the dyno?

four things, I normally top out at 3, but there are so many loose ends here,,, why not add one more

1) I am always suspect of any engine build where the actual static compression is not so solid it is written in stone
2) the OP says he degreed the cam, OK, at what?
3) I would think a 383 would make power beyond 5300 RPM
4) the comment about the dyno ( post #20) is extremely valid, different dynos, different results. Especially considering the operator did not spin it past 5300, for some reason.
