Yeah, if you do everything and he does nothing but show up you might come close.

Sneak a shot on it otherwise.

Seems you forgot to mention that little detail at the beginning.
Ya, your screwed.... Back to the distraction drawing board!!!

Try not to use a pro tree... If your dad runs 9.90's all day he's been on the pro tree for years... The bracket tree ( sorry cant remember what it's called - umm 500 tree) will probably boar him and throw him off some.

Turn off all traction and stability controls.
Have less than 1/4 tank of gas.
Remove as much weight as possible.
You can also remove the exhaust to remove weight, don't expect to gain power.though. You could get real serious and remove the rear seats.
e85 gas if possible, otherwise run the highest octane in your area. Run a tank before if you can and race at the end.
4wd launch(worked for me, some think it doesn't help the 5.0).
If you 4wd launch, over-inflate(45-50psi cold) all your tires. 2wd over inflate the fronts and drop a little pressure in the rear.

You could sabotage you dad a little bit by adding weight to his truck or lower his tire pressure LMAO! Better let him know when you're done though

Install a craigslist nitrous kit, 75 shot should be enough to beat him and not do damage to your motor.

Since I didnt get to go today I may try the e85 thing. Right now my truck says 31 miles to empty so I am thinking of going and putting 1/4 tank of e85 in it. Does anyone know the mileage drop I will see with the e85? Everyday driving for me Im seeing about 16.5-16.9 mpg

Fueleconomy.gov. It's all there, just look up your truck.

mechanicboy

About 25% drop, it will go back up when you switch back to regular.

Somewhere in the 13 to 14 mpg range.
