Ron (accobra) & all, another interesting intake manifold

I have seen nitrous plumbed like this also.
Whatever the purpose you need to keep the tubes away from the carb linkage.
The pantera linkage is a little different since it needs the center pedestal so the accellerator can pull it.
That doesn't leave much room for the vacuum tubes.
The first few batches of Hall manifolds all had a 1/4npt hole on the valve cover side of intake port #8.
That is where I get the brake vacuum and vacuum advance from. Is it scientifically correct? Probably not but it works well enough. I try to leave well enough alone.

Yes Swagelock is good enough for any auto application. It's a higher quality tubing fitting than the AN, DIN or the SAE flared stuff. The pressure ratings are way better than the tubing connected to it.

You could dump the pcv into one side of the exhaust if you want, or attach it to the rearward distribution block & those 4 cylinders.

Either way, I would run the brake booster & vacuum advance off the 4 forward runners. If you run the pcv out the exhaust, then you only need the forward distribution block, tubed into the 4 front runners, nothing plumbed into the rear runners at all. Make sense?

Plumbing the brake booster to 4 runners instead of only one provides you with a better vacuum signal, that's all.

Getting tubular with my pal on the DTBB

Ron, run an open pvc, no more smog for your car in ny

An open PCV meaning two breathers or cap and breather ?

Technically you need a pcv but is your guy really going to look? This is like the old days with just a safety inspection for $10.
I think the '79 makes it under the wire too.

If you can't run a pcv to the intake manifold, run the exhaust aspirator set up. You want to positively ventillate the crankcase some way. Don't just do the 2 crankcase filter thing. that allows blowby to collect in the crankcase, pollute the oil, chew on your bearings & cylinder walls, increase motor wear.

George,

That was my thought ... I have to do something to exhaust the fumes ... Ive seen a few motors in my time where the PCV was not working and they were loaded with flakes of oil deposits and such. Maybe one from one side to the header and a breather on the other ?

Ron

Yes.

Draw crankcase fumes out & allow plenty of fresh air in. Don't want to draw a vacuum on the crankcase with a wet sump, the oil pump would stop pumping oil. So the Breather on the opposite valve cover must always be big enough to flow plenty of air, more than the pcv or aspirator can draw out.

Venting with my friends on the DTBB

Na, the race cars all suck oil into the headers, great in theory though.
By the same token you can't run a pvc in a race engine either, especially a Cleveland.
You'll suck in some much oil you'll think you have the James Bond car and are setting a smoke screen.
