Can I use B or C body manifolds fore better flow on my sleeper GTS?

We could get sneaky and plumb a fogger into the bottom side of the intake but this isn't that serious of an effort. Most of what I have in this car aside from the body itself is left over from my red '66 charger. I have pondered whether a fogger would help or hurt over the plate. I would think a lot of that has to do with how balanced the intake manifold distribution is.
Agree. The advantage of a fogger is being able to control mixture on each cylinder. With a plate, you are at the mercy of the plate designer and the manifold distribution. Primary reason to use a single plane intake with a plate.
(For giggles, I wonder how bad the mix would be with a couple plates..... on a crossram? Hiding a fogger under a crossram would probably work MUCH better......)
