Perhaps a "stupid" question, but that's not stopped me before!
I have an early '56 T Bird with the air cooled converter. When I replaced the left exhaust pipe off the manifold, I failed to leave enough space between it and the air intake "scoop" on the transmission case, and I get a very annoying vibration at times. If I turn the scoop around so that the opening faces the front of the engine and the air is forced into the cooling path, I pick up the needed clearance. The cooling air flow remains the same...in the scoop and out the discharge on the right side. Am I going to cause an unanticipated transmission cooling problem by what I've done?
