Breathers and PCV - What is the ideal set up?

[Shawn Strunk]

What is the ideal setup for valve cover breathers and a PCV valve? My motor is a 355ci SBC with 400hp. What do I need and still have a clean look?

Thanks,
Shawn

Good question. The way I see it, you basically have 2 options: 1) pull a vacuum on your engine or 2) vent your crankcase pressure to the atmosphere.

The preferred way is to pull a vacuum, but it's not always the easiest- and there are alot of good and bad ways to do it. The type of driving you do can make a differance.

The easy way is to vent to the atmosphere- and there are several ways to do this too. (You may get sick of smelling the fumes though)

What type of driving do you normally do?

The car is being built to be a street car - one you take out on only nice sunny days for a cruise, and maybe attend an occasional car show. Everything on the car is so overkill as I am building it with the best protouring/racing parts, but in actuality, it is basically a show car. I have looked into this subject and it seems I should put a PCV valve on one side, and a breather on the other side? Is this sufficient?

Thanks,
