With the exception of the Grocery Getter Guys does anyone have any experience with track testing the Offy manifold??
Maybe I'm missing something but I've ran them several times on different applications, all three square bore versions and a low rise dual Q-jet and never noticed any kind of gain over a single four barrel other than the Offy liked to RPM a bit more. The best set up was welding the rear halves of two manifolds together to get rid of the big bend in the front runners.
Back in the day my buddy went back and fourth between the Offy 2x4 and his tri-power and they seemed very close in performance. The tri-pwr seemed to have more mid-range and the 2x4 rpm'd a little higher.
A guy that works for me runs one on his Olds because they look cool but pretty sure his four barrel set up is faster.
