Jerry Panteleri fabbed a set of restrictors for my 351C pushrods back in 1994. It was an exercise to reduce flow to the top of the heads and keep more pressure on the main bearings. As I recall we reduced the orifice down to about .020. A fond recollection was starting the motor with the valve cover off and seeing the oil stream out of the rocker and hit my garage wall over 10ft away.
I abandoned the restrictors later as I discovered that the easily clogged with random pieces of RTV, etc.
Actually still have them with a very cool mini slide hammer Jerry made to install and remove.
I'd like to try the clear valve cover because I think that I would have to see it to believe that the valve covers could fill up so much quicker than they could drain. The area of the drain holes are so much larger than the area of the pushrod holes.
I see sets of 351C stock valves covers for sale ALL DAY Long at $50.00 or less on Craigs List/ eBay...small price to pay in my way of thinking to ACTUALLY SEE what is going on!
I'll donate $25.00 towards your experiment if you make a video to document the results...Mark
As Bosswrench mentioned, "seeing" what is going on aids in finding a remedy in this case.
Matches up to the current generations point and click theory of computer graphic solutions.
In the "B.C." era, engineers actually needed to be able to picture the issue in their own heads.
The clear SB Chevy valve covers were pioneered by Smokey Yunick. At least he was the one that got credited to it? Kind of like Columbus "discovering America" I suppose?
I think though that "you" need to realize that "you" would have to be in a very small group for the volume of oil in the valve covers to be of "major importance".
It really is only happening over a period of extended high rpm use. One that would most likely be seen here in the US at high speed events, not legal US highway operation.
The BIGGEST concern is running the stock oil pan out of oil. The simple fix is using an Aviad 10 qt oil pan. Then there is enough oil in the system irregardless of what you do with the car.
Siphoning oil into the intake manifold is secondary and actually has some benefits.It isn't necessarily an issue.
Pressurizing the crankcase negatively is the more important aspect of that system. Then there are secondary issues that go along with that such as finding a pcv valve that actually opens and closes at the timed points where that is needed not the least of which is finding one that actually completely closes at idle.
A single 4v intake manifold, although not without it's engineering issues for that, is easy compared to an eight stack system.
Probably just about anyone with rudimentary knowledge of what is needed can plumb the Pantera to have those benefits? (I'm thinking about me here, not anyone else so don't take offense) In my perspective, I think though that the art is in having it NOT wind up looking like the "Back to the Future" Delorean but to each his own? That COULD be someones objective after all?
Good engineers always bring in an independent individual or group, i.e., a consultant. Whether actually in the process or soon after they think the initial criteria has been solved to review what they have done and to verify they haven't overlooked other criteria that should have been involved to begin with.
I can't help but think that a 427 Cobra looks so innocent just sitting there? It's like a 2500 pound cruise missile. You don't want to be around when it goes off?
Some people are that way too? At least here if there is an explosion, we are all at a safe distance from the epicenter...theoretically that is?
