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 :-)

Oh, by all means, my way is not necessarily the only way, or even the best way. It's what I learned, from 40 years of working on QuadraJets, and from guys like Ashley, Oliver, Bridges, and Schindler.


The QuadraJet is very sophisticated. I suppose for many, eliminating the power enrichment circuit simplifies things. I prefer to use everything it offers.


Your mileage may vary.
