    I have just bought a 58 Plymouth Belvedere conv that was modified in the sixties for drag racing. The car is largely unmolested, with some period modifications like fenderwell headers, four speed trans behind a very healthy 64 383, SW gauges, buckets and other small stuff. In the engine compartment I found this control unit, and don't really know what is for. Any help here?

  9. My 429 Cobra jet came with a factory installed version of one of these things. The first time I took it to the drags I bypassed it. Drove home on 7 cylinders as one of the pushrods jumped out of the lifter. I guess Ford knew the limitations of the valve train.
