[QUOTE="73inNH, post: 395467, member: 7611"] An update . . . Thinking about the PCV and how when I connect it to the PCV port on the carb, the car bogs (running lean, likely), I decided to plumb the PCV into the air cleaner base. As I was looking at my setup, I remembered that the PCV was originally plumbed into the stock air cleaner housing, not the carb. When I switched to the Edelbrock 14" air cleaner, I plumbed it into the carb, which caused the bog. So I bought an elbow and a grommet, drilled out a hole in the air cleaner base, and run a small hose from the base to the PCV in the valve cover. This worked. I now have the PCV connected, and the engine runs well. I still have a very small hesitation when mashing the throttle from low RPMs. I may buy the E[URL="https://www.edelbrock.com/accelerator-pump-nozzle-kit-includes-024-033-043-nozzles-and-gaskets-1475.html"]delbrock accelerator pump tuning kit[/URL] to give it a bigger shot, but the problem is so small now that I'm in no rush.
