No single plane

Yes! I understand that already! Got it! Roger that! Next!

Dual plane only
Divider can be cut out
Floor cant be modified

Yes! Got it. I understand! We’re going around in circles here!!!!!!

Read carefully… again…. Is any dual plane OK?

Im asking, must you use a stock dual plane intake?
Can you use an after market intake?
Must it be era correct? As in regulated by class rules.
Example, “Must use available intakes no later than 1975”
