250Nova,
one thing to consider,,,, the bolt in lump port that Larry sells.
These will greatly increase your torque & HP & better all around driving.

You should run the 292 pump,not sure on the year,,,,anyone????

Run a 3/8 line from the pump, to a fuel log ,then run your (3) 5/16 fuel lines to your carbs.
Remind us on your goal about deciding on an electric fuel pump or mechanical????
What compression ratio are you running?
