lowering 60 foot time

I agree with Adam and Oldvart on the cam versus compression theory. But as for the larger squirter, you
might want to try moving or changing your pump cam
a bit first. You may be half way through the shot when staging.
As for cranking up the torsion bars, I would recomend against it. I think that would worsen things. My theory is that you want your front end to rise, thus transfering weight to the rear tires. (Things in motion,.... so forth.)
Try 6cyl bars like oldvart suggested.

good luck.
