Valve cover evac

I have always run your standard out of the valve cover to the collector evac tubes. I just bought a new set of valve covers and figured I would throw it out there and see what you guys thought about them or if there’s a better solution. It is an alcohol BBC with no vacuum pump. I normally have them out of the front of each valve cover

Invest in a vacuum pump just my 2 cents

Vacuum pump will pick the car up too much. I’m already running a throttle reduced plate to slow the car down.

I run a BBC 540 with the EVAC tubes.
Intended to put vac pump on many years ago, just never have.
We run alky, I use the sealed adapters with the ball check valve out the standard location valve cover hole, located on the front end of the cover.

It still works "OK"

Using #8 soft black tubing

I can't remember the name of the company that made the fittings, they are out of business now anyway

Mine don't have those tubes. Have a line tapped into the valley part of the intake, a PVC valve, more line and tapped into the intake right under the carb. This is a 494 Olds stroker motor but has worked for years this way even with near stock motors. Never tried a vacum pump.

Your oil will thank you if you install a vacuum pump
