Well the valley pans on the pre 1967 motors (326,389,421) are lower in the front and have the pcv valve in the the rear.
The lower pan height in the front means the Intake Manifold runs a tad cooler due to more air passing under it and the front mounted PCV can be made to work with any Carb set up and is needed to run trip's.
The only down side with a Q jet Carb is more exposed 3/8" hose if you run it top side.

I'm sure you meant to type rear when said front on the trips
