You'll need to estimate or know your initial torque to start with in the Fuel Wizard. You can also go to an 80# injector if needed from the stock 62#, but I don't think you'll need them.
I would setup the system as a linear vs. rpm based becasue it'll be much easier to tune. The PIII forum
Professional Products Forum is a very good place to get answers to your questions.
Are you getting the latest ver. 3.0 with ignition timing? I think that's what's being offered now.
Your fuel lines should be more than adequate. Run the system with at least 45psi and you don't use the vacumn port on the regulator. I adivse using the return line as you do and not their returnless system.
As for HP, the EFI units will produce more HP and better driveablility than any carburator can give. Try running your carb'd engine at high altitude from sea level and see what I mean. No changing jets in EFI, saving and installing different setups in EFI makes tuning easy. Everybody has their choice and that's my opinion. I've been through the entire gammit from carb to EFI in my career and EFI is better imo.
You should be able to pickup and unit in the $1500 range. I'd also run an in-tank pump as they are quieter than outside the tank and EFI uses pushers not pullers so the pump would have to be lower than the output (or equal to) of the tank.
