Not if you plan on having any belts on it. The pulleys will not line up and then you would have to try to find a pulley that would work....and if you try to extend out your crankshaft pulley....you may have an issue with the cradle now getting in the way....and forget about doing anything with the power steering pump pulley.
Honestly I do not see a reason to change it to a longer one...but you did not add anymore to your post but a basic question....so it is all guess work.

Short pumps come in two different lengths/hard to notice/ from the back cover of the pump to the engine block depending on the year----I think....the correct pump will bolt on without having to add extra gaskets.

Corvette - Unique in Water Pump Ways
To be precise the water pump for a 71-82 small block Corvette is neither short or long;
Short Chevy Pump = 5/8" pilot diameter & 5-5/8" block to hub distance
Long Chevy Pump = 5/8" pilot diameter & 6-15/16" block to hub distance
Corvette Pump = 3/4" pilot diameter & 5-13/16" block to hub distance
Short Chevy Pump = 5/8" pilot diameter & 5-5/8" block to hub distance
Long Chevy Pump = 5/8" pilot diameter & 6-15/16" block to hub distance
Corvette Pump = 3/4" pilot diameter & 5-13/16" block to hub distance
