Best performance for the least money

What in your opinion would you say is the cheapest way to bring the horsepower of a 5.0 engine up to around 325 horsepower?

To the ground or to the crank?

master power 60-1 turbo, BBK shorty headers flipped, JC whitney charge piping, 3" JC whitney downpipe dumped, FMU, MSD BTM.

2115 plate kit

Or, explorer Intake/P heads, full exhaust, and carefully pick your cam for 325 at the flywheel...

I was thinking 325 at the wheels

intake, exhaust, u/d pullies, and a 100 shot, thatll get it to the wheels.
