Manifold Question

They do work fine.

You also have to understand my background with this. I have always played with towing/truck/motorhome motors in general. What I see at 50% throttle, you would never see in a street car.

I was merrily stating that in all of the manifolds I have used, the 7 was the worst at fuel distribution, under heavy service, that is. Still a decent manifold, just like the rest of them. The best, under high throttle/heavy load settings that I have found, are the 360* offenhausers, and the street dominators. More than likely because they are the low RPM single plane design, much like the first LA manifolds.
