Simple - more duration, more converter flash, more rpm
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.
I think many discount what Jim at RB does if you just call him. He's a sharp dude and he doesn't do a lot of BS on trick of the week junk. It took a ton of phone time, flow sheets and some serious consideration of valve job shape and angles before he decided on a lobe/rocker ratio for me and it was worth it.
You can always add some stroke length to your engine combo to keep RPM down to a reasonable level. Today, valve train, lobe design and spring technology makes its pretty easy to turn something 8k and still have some decent reliability.
Is the extra 60 pounds to make the car more racer friendly, or is it because the driver is more dinner friendly?? Asking for a friend. He says the same thing. So I'm looking for a third party to verify.
TIA.
