Lots and lots of great info here, thanx for sharing it all fellas .

There are many different ways to skin a cat .

I like closed PCV systems and usually ad them to my older engines .

For those who are lucky enough to have undented rockerboxes, the solution is simple : look in the AC / Delco "buyer's Guide" and choose the oil cap with a large hose nipple on it and use that to draw clean filtered air from the air cleaner .

PCV systems are nice on several levels, they make the engine last longer and reduce oil weeps & seeps at the same time without sapping any power .

Never forget that older GM engines were well designed and usually run well long after other brands engines have stopped running .

Upgrading an tired old oil burning engine to breakerless ignition will allow you to keep driving it as you $ave the $ for the overhaul or rebuild .

Sharp tuning is critical ~ because of slight difference in manufacturing tolerances each engine can be fine tuned to give it's very best .

Gasoline is never going go be cheap again to think hard before Hot Rodding your engine ~ a 3/4 ton stock truck camshaft from 1967 really wakes up the average GM V8 and still provides good running, easy driving manners and fuel economy you can live with .
