How many is too many?
This engine has either had a Six Pack or a tunnel ram on it after I rebuilt it in 1979 the first time. It has been in a 70 GTX, 70 Polara 2Dr, 69 Dart, 70 Cuda, 110" FED and this 75 Duster. It's almost ready to light up with this 850 Pro Form. I had to cut a wedge of metal out of the linkage arm and re weld it to get proper geometry on the secondaries. If you adjusted it for proper WOT it would kick open the secondaries at idle position. Probably why they were so cheap on Ebay...
