I’ll agree with all the above except for more rpm. Jim at Racer Brown loved when I called for cams as I would give him an exact number on stall and head flow test numbers at every .050 instead of .100 lift. My 408 on BP 93 Ran 9.80’s shifting at 6400 rpm with one of Jim’s tweaked .520 lift cams. This was a Econo W2 headed combo that I did some mild porting work to. Heck they still had the 3/8 inch 2.02 valves in them.



What does that duster weigh? more of a curious Question.




back then 2800 pounds. 2860 now as I keep making it racer friendly.
