What are you guys doing for crank case evac / PVC?
I have a breather in each valve cover of my 383. The breathers are misting oil during extended WOT. It's especially bad if I use the nitrous system.
I'm thinking of installing a catch can, but I'm not sure that is going to solve the crank case pressurization issue. Anyone here had luck venting to the exhaust on a car with mufflers?
Anyone here figure out a vacuum pump solution that is daily driver friendly and won't put me in the poor house?
Other suggestions?

You aren't boosted, so why not run a normal pvc? I'm using 2 breathers too and will get a little oil on the drivers valve cover. If it gets worse, I'll probably do the catch can method.
