PCV- Good or bad idea for a performance engine?

If you even think about driving on the street, leave the PCV system intact. Your carb is already tuned to have it in place, besides you need to adjust the mixture with the jets not the PCV system.

The Moroso type collector scavenger systems only work at high RPM full throttle.

If you have more blow-by at idle than the PCV system can accomodate your rings are letting compression escape. (With the PCV connected if you cover the breather with your hand, the crankcase should build vacuum in 2-3 seconds).

If you just vent into a puke tank, you will likely discover 100 new oil leaks.
