Default Adding PCV valve to 351W - Side Effects?
I have a 351W (Ford Crate, built by HRE) to which I would like to add a PCV valve. The engine has a dual plane manifold and a Holley 80508 750CFM carburetor. If I install a PCV valve is there anything I will need to change or adjust? Will the mixture lean out so much that I will need to rejet? Will I need to adjust the ignition timing? Anything else?

Thanks, Bob
