I never saw anyone running an Offenhauser Tunnel Ram in any class at the drag strip in the 70s and like said above only saw one on the street. I still have the Weiand Tunnel Ram in the basement and have two top pieces for it.
I ran that intake on the street years ago on a 440 and it was great! Gave the car killer looks and it performed very well! The long runners seemed to help the bottom end. Engine idle speed was nice and low. I liked it! Two 600 Holleys, street Hemi cam, stock 906 heads w/6 pack springs and cheapo headers... stick car
