What Converter for this build?

[Dave22443]

Hey guys, I'm in the final stages of my engine build and I need to get a torque converter.  Problem is, I'm on a budget and I have no idea what to get.  So here are my specs.  Maybe one of you can reccomend something I'd be happy with? 

1973 440 engine
Bored .060 over
Compression raised to approximately 10.25 to 1
Stock heads
Intake valve enlarged to 2.14
Exhaust valve enlarged to 1.81
Cam = Voodoo Lunati @ 261/267 - .555/.556 (LUN-60330)
Intake = EDELBROCK  PERFORMER 440
Carburetor = 800 CFM Holley
Double roller timing chain
Stainless 1.5 Adjustable Rocker Arms
Headers
Stock Rebuilt 727 w/Trans-Go T2 shift kit installed
Rear Tire Size = 295/50/15
Rearend = Mopar 8.75
Gear Ratios available = 4.10 or 3.73  (Undecided on final choice, both available)
Budget = $300
Use = Street
Fuel = 93 Octane pump gas

Bonus Question:  Any idea how much power this setup will have???

Thanks!
