I didn't mean to imply that it was some kind of speed secret to eliminate the primary rods.
I've run the same stocker, both ways,... true foot braking it to about 2800-3000 , and never saw a bit of ET movement, either way.
So, the answer is, once again...It depends.

On a Sportsman bracket car, where two stepping is not allowed, but deep staging is, keeping it clean at about 1500 is a good idea.
As mentioned, there are many ways to go about that. A modern, multi-spark ignition goes a long way here.

Stick shift car? Different world, but I've never seen much difference here either.

Bottom line..Pick your poison , and don't stop till ya get enough :-)
