...breathers and pcv breathers.

Where did you get your breather cap and pcv breather cap from? Also, what type of rubber grommet did you use, open or one w/ the slant airvent cut one?? Lastly, is it bad or harmful to the engine if I just simply run two breather caps and just keep the PCV valve plugged on my 1405 Edelbrock carburetor? I'm trying to get my '67 running.

FYI: It has a '78 350 shortblock motor.

Re: ...breathers and pcv breathers.

You need to have a PCV valve on that engine. If you don't, the crankcase pressure can cause all sorts of problems. Just use a PCV valve in one hole, and a breather in the other. A standard round grommet should work just fine. Most parts stores usually have this stuff in stock in the accessory section.
