With a performance-tuned engine sporting long duration cams and a low velocity intake, you would say it was "off the cam" down bottom; You could even get a backfire if you opened the throttle too much down low. But like I mentioned here earlier before, an Otto-Cycle engine (your 4-stroke) at 1200 rpm is firing each cylinder 10x per second**, multiply that by 4 cylinders = 40 power pulses per second ! Back in the 1930's with big bore, long stroke, very low compression engines, that would be in the middle of the power band!
** example: 1200 rpm / 60 sec per minute = 20 revolutions / second. Then divide that by 2 (as in a 4-stroke you only get a power pulse every other time around) = 10 power pulses per second per cylinder.
So on a V8 engine with 8 cylinders you get eighty power pulses per second.
Lug that! General duty V8's should be tuned to make good torque++ from 900 - 3200 rpm. like the old days.
++ approximately 1.2 lb-ft per cubic inch displacement. So a 350 V8 should make 420 lb-ft at say 2600 rpm.
