An electric pump will help a carbureted car start a little better in the cold weather. It also cleans up the engine bay a little bit. I doubt if there is any noticable power gains from removing the manual fuel pump. 
It all depends on your fuel demands. If its a street driven car and some mild work then a mechanical is fine.
an electric is great when you need a high flow and especially when you are revving high and or running juice. it does free up some HP from the motor

I swapped over to a holley red fuel pump a couple years ago. Simply bolt in, wire up, and go since it runs at the correct psi for a carbureted system. I was having issues where the car would die in a quick turn, and after swapping from a stock replacement fuel pump to the holley red, I never had those issues again.
If what you have is working fine with a mild motor, don't fix what is not broke. The benefits are small on a mild setup.
That said if you are doing a new fuel system for adequate supply & power savings / efficiency then yea go electric. One benefit of the g-body over older muscle cars is that some came with fuel injection so the parts new & used are out there to cheaply and easily upgrade to modern in tank electric using a used GN/Type/TBI Monte tank & fuel pump hanger/sending unit or aftermarket replacement. Oh yea if you are using a carb you also need a return style regulator such as the Mallory 4309. Tanks etc are available on eBay and the plug n play pump & wiring at http://WWW.racetronix.com. Its cheaper easier safer quieter and will last longer than the old conversion method with an out of tank gravity fed electric pump & sump or cell that you commonly see on a home built drag car.
For street car the biggest benefits are that its safer ie no pump hanging between your tank and bumper for a rear end accident fire hazard, its quiter no loud electric pump noise as its inside the tank covered in fuel, and last the pumps last much longer.
