How high can you footbrake your engine against torque converter/brakes? At what RPM does your wheels break loose?

That varies from engine to engine, car to car, tranny to tranny - combo to combo.
I can't foot-brake the Camaro above 2100, but with the park brake on first, I can get it to 2300. I can hold the '57 at 3000, foot brake and just the primaries. But the converter will stall to 3500 if I have the park brake on and open the secondaries. More cam and it probably won't stall that high (but, maybe it would...).

I was curious.....I can hold 2200 to 2300 RPM with foot brake and 3500 RPM with foot brake and emergency brake. Looks like I am going to need to do the proportioning valve trick.

About 2300 rpm, standing on the brakes. With my supercharged BB engine/tight torque converter/lots of traction combo, this thing wants to GO. I could never break the rear tires loose with the brakes on, unless I used the line lock and/or the rear tires are in water. It has so much low end torque, when cruising on the street, I just leave it in third gear all the time (manual valve body).
