Big Block seems to slow

Does the gas pedal open the carb all the way
Do the secondaries open
where is the timing, does it ever ping? crank it up!
what rear end gears, 2.76 sucks off the line
What cam, stock small cam? Lumpy and Too big?
How much idle vacuum.

many things to do to wake it up.
Well guy said it had a small cam in it but is also the same guy who had a copper tube rigged for a kick down so I’m sure it’s stock. Going to run through the rear gears and compression test today.
