YEEEEHAAAHH!!!! and UH-OH

Last night I installed, tuned and test drove my new Mighty Demon carb.
WOW
What a performance increase! I must have gained a whole bucnch of power. Not knowing how to quantify it other than the pucker factor went from a 4 to a 10!

Problem:
After the run, I was blowing oil out of my rocker cover breathers. Anybody got any ideas?

Maybe you should try the set-up I have (see pic below). Cobra Valley http://performanceunlimited.com/cobravalley sells the billet breathers and catch tank. Just add some steel braided hose and fittings for a clean appearance. Connect the passenger side to the vacuum fitting on the rear of the carb, and the driver side goes to the tank (mounted on the front cross-member). The tank has a filter breather top to remove any vacuum effects. I never get one drop of oil on the valve covers with this set-up, and I'm running a Mighty Demon, too (great carb!).

Mike,
You are building pressure in the engine, do you have a PCV hooked up to that new carb? if not you'll need to install baffles in the valve covers as the pressure will be forced out there along with some oil.
