A theoretical question....I've been wondering....always a scary thing. On V8s, Edlebrock, for instance, makes dual plane Performers and single plane Victors manifolds. The dual plane has much better off idle and street performance, while the single plane Victors and others are higher RPM manifolds.
My Clifford is single plane with big honking runners that don't promote high mixture velocity. I was looking through the Santucci book at all the old manifolds and they all appear to be single plane.
I don't plan on doing this but WHAT IF, someone were to do something like this:
The black lines is a cutaway of the standard Clifford manifold. My Edelbrock sits sideways anyway, that is the secondary is parallel to the crankshaft. Actually it's closer to the engine rather than as shown but the principal is the same.
The red line would be a piece of aluminum... say 1/4" flatbar that is welded in the middle of the bore as shown. It wouldn't have to be welded full length to be effective. Given the firing order, I'd THINK this would isolate each cylinder from the others, increase mixture velocity, and add more low end torque. Of course, if you've removed the stock boss this wouldn't accomplish anything.
Any merit to my thinking????
