850's?

I've never heard of 850's with automatic chokes unless they are a spread bore? Either way it's more than double what should be used and probably hurts driveability over two 600 vacuums.

If that's a dual plane Medium Riser intake you shouldn't really have them sideways. Mounting them that way makes awful distribution.

Is that the car in the little picture ? The red one? Pretty cool, nice to see Ford powered hot rods
