10's on $5,000 ?

I disagree. why do you insist on doing it the hard way. lol
5000 dollar budget would be perfect to reach your goal with your Duster. A BIG BLOCK DUSTER :thumbsup::D

Not if the price/value of the car is part of the $5k.

Which was/is the original premise.

You have nothing but $5,000 in your hand....... no car, no parts, nothing.
The idea is to go from zero to <11.00 without exceeding that $5,000.
Building a 10 second car is easy when the money is ever present. Anyone can do it. In fact, you can hire it built, buy a car already built, or order every component and just bolt the components in such as crate engines, tranny's, and even Dana 60's all set up. I like the challenge myself, and am attracted more to roadkill looking type cars more than 40k dollar restored 6 pack cars. But that's just me....
