School me on Stock Eliminator?

If you're competitive in SS/K, let's assume you run almost a second under @ around a 10.75 E.T. That's A LOT of HP out of a 273, about 550 by quick estimate (assuming 20% driveline loss) and roughly 2 HP per cube. Those RPMs must be sky high, I'm guessing over 8K?

Realizing that S/S allows more engine mods than stock elim., I'd still like to know HOW THE HELL DO YOU COAX 550 HP OUT OF A 273???? :dontknow:

Calculating HP for J/SA looks like it's around 465 at the flywheel and 350+ at the wheels to run 11.75 or so. Not too shabby!

See, this is what's got my interest piqued on this subject, this is cool.
