PCV valve removal. My car runs better when I block that port on the intake runner. Any wrong with NOT having PCV as long as I have a breather in one valve cover. I suppose I could maybe find a good port at the base of the carb…. Then all cylinders would run a little leaner instead of just one. I’d like to just do away with it.

You need to suck the gasses out of the crank case. Bad things happen when the blow by gasses collect in there. At least that's what I've heard.

X2. Better for the motor if gases are removed. If running a long duration camshaft you may have to use a valve from a high performance engine to better control the vacuum leak the valve creates. I’m using a Fram FV178. Valve was used with the most radical Chevy engines of the late 60’s, early 70’s.

You might also check for a vacuum leak.

I know what you mean. If you don’t have the stock set up…manifold and elbow, you tend to lean out a cylinder.

I added a phenolic spacer under my carb. I drilled a hole (1/4”?) and added a nipple directly between the two front primary holes so that the hole opened into both primaries. It’s been working fine for years.
