Wow - I was wrong....maybe I was reading a base RPM ? Anyway got the mags back out to re-read and both were talking about 8000 to 8500 RPM after putting in stuff like 392 Hemi valves (cut down a little) and other stuff. The first mag is - Modern Rod's issue May 1965 with discussion's on the Dart Charger with Ed - Mr Isky grinding out a cam. That issue is on phase 2 of the hop up. The next mag is Speed and Custom's Aug 1966 with still more info about early 392 valves with grind info. The article follows some stuff the Golden Commandos did to - "Gold Fish " running their F/SA 1965 Cuda as well as the "Politician " another 1965 F/SA Cuda. The D-Dart of "Gendarme lll " running D/MP class was in the other mags as well. And the next is Rodder/Super Stock issue Jan 1968 with more on those 392 parts and some neat piston cutting. There was a rail job called - Silver Bullet " that was running a home made fuel injected 273 . They also talk of swapping sides of the pistons which they say gains some HP.
