Lookin' for 11-second times from a K10, what's it take???

[Swiftshifter68]

Alright here goes, I'm gonna' post this question here so we can get an idea of our competition. A neighboring shop owner has a shortbed, half-ton, 4x4, NP205 granny box, "Small block" (all he'll admit to, without my lookin' it over. I'll just guess it's a serious 383, Dart 230 iron heads, solid roller) The guy's EXTRA secretive about the combo' and has indicated he'll be at approximately 3200lbs, raceweight. (?)

We've got a $500 bet (apparently he's good for it, not just flappin' his gums) that his truck is gonna' beat our friend's '67 Dart in a drag race, at a bona-fide dragstrip (forget street racin' for a minute). The Dart's packin' an Edelbrock-headed 360, Comp XE275HL cam, A727, 3000 stall, 8 3/4" 3.91's. Raceweight, wet, with driver is right at 3100lbs.

The question is: What is it gonna' take/what should I look for on the truck, to indicate that the truck has a chance at winning. I've got a few ideas and we're pretty confident, but your input would be much-appreciated. I'm a Chevy guy myself, but our competition is pretty smug and has had his head blown up beyond belief, regarding how "unreal fast" the truck is.

Thank you to anyone and everyone for your input!
