If you want a larger cam try Mr Six Pac or Dwyane Porter.





I believe the distinction has been drawn that a Big Block Mopar with exhaust manifolds benefits from a cam center line somewhere around 112-to-114 and exhaust duration not much more than 284.

Andy Finkbeiner's dyno testing seems to confirm this as well as the track tuned Mr. 6Pack cam from Bob Karkashian.

So there again, the Mr. 6pack grind I decided to go with is optimized to run with bone stock 906 heads and HP manifolds. It's center line is 114 and has exhaust duration somewhere in the ballpark of the stock Magnum/Road Runner cam ~ 284.
