Pcv catch can

[JOATMON]

I've done a top end rebuild on my LT1. I had multiple sources of oil contamination in this thing,(intake gaskets, rocker studs, etc.) I covered some of the rebuild in another thread. After the rebuild I eliminated the PCV system all together. I've got both valve covers tied together with Moroso breather caps(the type used for pan evac systems) through a 5/8" hose routed down to the air filter. It's basically venting similar to the setup on boat engines.
Fast forward..... I do have a bit of blowby, it doesn't smoke out the breather tube but there is some crankcase pressure. It has pistons with the thin low tension ring package. It's a drag motor build. I think I may benefit the ring package by putting some vacuum on the crankcase. BUT, I don't want any oil contamination whatsoever in my intake track.
My options are an electric vacuum pump that would produce vacuum on the crankcase at all times with a catch tank on the pump discharge. This is the expensive option.
Or using the engine vacuum (9") and tie the PCV system back together using a catch can. This would be a less expensive option.
But, my thinking was that under wide open throttle the engine vacuum would be 0" and allow the crankcase pressure to blow back into the intake tract through the breather line thus contaminating the intake and being right back at square one.
What are you guys doing with drag style engines?
