1. Maybe 15-25 rear wheel horsepower.... ok, maybe 35 rwhp.
2. Yes.
3. between 12 hours and 3 weeks depending on your skill level.

edit... the bigger question is can rex/regina handle the additional airflow?

Do you constantly roll your windows up and down while driving? If so, then yes there will be current used and I guess if you did all 4 windows at the same time you could be hampering performance.

Depending on how you wire it, the fan shouldn't be on all the time.

I think they are pulling your leg man.

I seriously doubt you will get more than 15 crank horsepower (130 total) with a head, cam and header.

Watch this series:

The biggest gain you would get is going to programmable EMS.

Isn't the compression higher on the engine also? 10.3:1 v 9.8:1?

Stock (crank) hp is 118 and torque is 140 ft-lbs.

Going to a VX(3) or advanced VX will gain ~15-20 hp or so, maybe more if you add a free-flow exhaust, but the bigger issue is the loss of ~15-20 ft-lbs of torque and regain the M cam torque. Advance the VX more than 3 deg, like 5-7 deg, open up the exhaust to 2.5" and try some moderately bigger injectors. I don't think headers will do anything with the simple addition of a 531 and VX3 except make it louder.
Again, not sure if the Regina can handle the bigger flow. LH 2.4 can, so a conversion would be one of your biggest improvements, that plus a chipped ECU.
