Mine was NOT a 73 car or motor or 4000lbs. It was a 68 formula S 4 speed with 27+ inch tires 3.23 gears and still pulling at over 6500 rpm. And the tach checked good to my Snap-on meter. You figure it out. Or are you math limited too. :poke:
Stock 340s dont rev 6900 in 4th thats 165 mph
Valve float way before that
Drag limited no shot
The amount of hp to reach 165 is crazy
stock 340s make at best 340 hp with the big carb downhill with the wind
my math is fine unlke your tach
