Im hoping to hit around 11.70 . also taking front bumper support off and of course the stock gas tank think i will be able to do it.

What I can't figure out is why any one would try to build a "drag-car" with a 2.73 gear.
I am guessing this is a sbc.
To run a 12.10 pass with a 2.73 that is doing very well and would require a very hard-core engine.
In fact I would love to see some specs. on this engine combo.
To add to this back in aug. he was running 13.75's with a 2.15 60 ft. time.
On Nov. 1 he says he is now running 12.10's at 113 mph along with 1.77 60 ft. times.
Pick a story.
