Default Oil Catch Can

My 68 that has an 84 350, has anyone install an oil catch can on theirs? This car diesnt have a PCV system, 2 small air filters on the valve covers. I would like to catch the blow by somehow how instead of it just venting off under the hood. I reseach the cans and having seen anything showing a hook up to these cars. Recommendations greatly appricated.

I have no PCV system on mine and have no problem with VENTING oil until I get in the 5500 rpm range. then just a drop or 2 on the valve cover.
does your valve covers have baffles in them?
you can run a line to your exhaust that will draw the oil vapor
I believe you can use a vacuum pump system
but if you are getting that much blow by you need a ring job. jmho

Remove one of the valve cover breathers. Install a pcv valve and attach a hose to it and attach other end to the large port at the base of the carburetor. Problem solved. PCV=Positive Crankcase Ventilation, meaning you're now sucking out crankcase pressure, instead of pressure blowing out, and making a mess, and putting more stress on gaskets and seals, and...did I mention making a mess.
