I have read the ads and manufacturers propaganda but can anyone tell me the real differences betweeen intake manifolds.
I am using in a tow rig for my dragster trailer.

Too many variables to be honest. However, traditionally, it is believed that a dual plane would be much better suited for your application. Single Planes are designed to take advantage of an engine built for top end performance, not mid range (but again, too many variables, which is why I tend to disagree sometimes w/the traditionalist's)...

If it's being used in a tow rig, I'd stick dual-plane for the reasons mentioned above. Single planes in a general sense tend to sacrafice a little torque for better breathing and better hp at higher rpm ranges.

Dual plane for a tow rig. Towing requires lowend and midrange torque not topend power. You will only hurt your performance by running a siingle plane.

The way to Identify and distinguish between the two is?
I assume the lack of a septum dividing the two banks? would make my stock intake a dual plane , and the edelbrock air gap would be considered a single plane?
My stock manifold divides the engine in half, one side going to only four cylinders

Correct. Dual plane has the divider, single plane does not...
