[6pack] Triple SU Size

[Greg Dito]

Listers,

Does anyone have some knowledge as to whether it makes sense to use 1-1/2" 
SUs (HIF38 or HIF4) on a Goodparts triple manifold versus 1-3/4"?  The 
1-1/2" x 3 has more than enough CFM capacity for the engine but because the 
throat is smaller I would expect there to be greater negative pressure 
across the carb jet resulting in a more thorough mix of air and fuel at 
greater velocity going into the combustion chamber.  Is my premise correct 
or not?

Thanks in advance.
