I think youll be well over the 3 grand range.

You said a high performance AOD. Thatll be close to 3 grand alone.

A set of good tires will run $600 or better.

Just a cam itself will be $300 if it doesnt require springs and a torque converter. But you did say a tighter TC later on. They can run $300 and up.

A mechanical locker is $500 and goes up from there with electric and air lockers.

A good set of gauges from Auto Meter goes for about $70 per gauge, not including shipping. 4 gauges = $280. A tach is a different story

Eddy Intake $300

Theres $2200 without the AOD... Not tryin to be an azz but I think youll have well over $3000 if you build it right
