All the fast 383 motors I've seen, built and help race had to be revved up(above 7000 RPM boogie) to go fast up
Post the duration at .050 lobe lift, lobe separation angle and the actual lobe lift please on all the cams you have that you want to use up
As far as my choice based on heads I have used I would choose the Eddy RPMs only up
