Drag Racing The TriPower Technique Question

So here’s something I have never heard discussed.
As you are watching the Christmas tree countdown are you revving the motor up with just the center carb or do you have all three open?

Hi Dick,
I’m trying to figure out exactly what you mean by “bending” the center carb to adjust it.

Thanks,

Engine Stroke And Its Affect On Total Timing?

Hi,
Curious to know what the 4” stroke of my 421 wants.
Does it prefer 32,34,36 or 38 degrees total timing or does cam design and head material affect it more?
