the clattery noise I hear going up hills must be the ping you guys are talking about! sounds like something metalic is broken or rattling around in the engine but only up a hill like a bolt in a coffee can - this definatly got better with each improvement in the engine tune in terms of ignition wires, timing, especially the timing; I was at 12 btdc now 6 per spec
Exactly. Since you're willing to modify the car, consider the GM HEI distributor conversion and a hotter coil. The flathead needs the most accurate and strongest spark it can get. Not only that, but many of the Packard distributors I see have worn bearings, worn centrifugal advance and perished vacuum diaphragms. A new HEI fixes all those problems as well.

I guess an air cleaner,is the wcfb an oil bath again. Does a later paper element breath better?
Yes, the oil bath works just fine and filters as well or better than the paper.
No, if anything, the paper filter has more restriction, but it's not enough to make any difference.
Maybe, consider a split exhaust manifold and dual pipes. Should sound great!
