Good Luck

 

blower, turbo, or nitrous

 

Accelleration: gears and a limited slip differential
Torque and HP: Supercharger or turbo charger and N2O
Torque: Stroker Kit
HP: P/P upper/lower intake and heads along with a cam swap

 

If your trying to budget id suggest
1) gears and an lsd(best bang for your buck besides n20, ir f/i
2)LT headers and exhaust
3)cai and UD pulleys

that oughta keep ya busy for a while

 

What is a stroker kit? and where can I find an affordable 1?

 

A stroker kit is a kit that uses longer and stronger push rods and pistons to allow for a longer "stroke" (the up and down length the piston travels).

www.supersixmotorsports.com sells reputable stroker kits, keep in mind, performing this kind of work is no wheres even remotely cheap. The entire engine needs to be disassembled, honed, bored (depending on the stroker size), cleaned, and then fully reassembled with the new kit, all in all, it's extremely costly for the power gains, however your block will be stronger than carbon steel (in a technical sense) and will essentially be brand new, aside from all the old parts that go back on.

 

you can pull a 4.2 v6 out of a 97-08 f150 and it will swap in
