I've come to the conclusion if I end up keeping my hatch I'm going to go ahead and do a 331 stroker kit for it. Who makes the best one and how much average HP gain should I expect from adding it to my car?

 

I should have specified what the car already has. Who makes the best kit too?
Ford GT40 crate motor
GT40 aluminum heads
E cam
30 lb injectors
Calibrated 75MM ProM mass air
BBK 70MM throttle body
Polished Cobra upper & lower intake
Polished Vortech SC Trim lbSupercharger
BBK shorty headers
Offroad H-pipe
2 chamber Flowmasters
2-1/2 stainless tips
2 speed electric fan
FMS aluminum radiator
180’ thermostat
FMS .373 gears
B&M ripper short throw shifter
RAM heavy duty clutch
Adjustable firewall clutch adjuster
FMS aluminum driveshaft

Here are some sites to gauge the kit prices for a 331 Scat Stroker.

 

There isn't anything wrong with Eagle parts if you aren't going to be pushing the limits of your engine to the edge and beyond.

Hell, even if you are, we have had two engines do very well with Eagle components. One was a SBF (Eagle 4340 crank, Eagle H-beam rods and Venolia pistons) that went 5.70's at Sunshine running at over 3200 pounds with a single fogger. This car was still driven on the street from time to time. The second was a BBC (Eagle 4340 crank, Eagle H-beam rods, Venolia pistons) that went 5.30's at Sunshine also at over 3200 pounds and a single fogger.

For the money, and as long as the parts are within spec when you check them, I think Eagle parts aren't too bad of a choice.
