The Power Plate had tapered cones under the throttle bores. The interior of the cones had 20 pitch screw threads in them. The cones protruded into the intake manifold by about 3/4". The engine coolant merely offset the evaporative cooling effect of vaporizing most of the fuel. This single device educated me as to the value of properly vaporizing the fuel and homogenizing it with the air.
Oh, and the power increase was like I yanked the /6 and dropped a 360 2-bbl in. Best of both worlds!
