Kind of an off topic car but I am trying to install Corvette valve covers.... lol.
I recently purchased a '32 Ford 5 window from an older gentleman who had owned the car for nearly 50 years. It was built in the early 80's so has some typical for the era updates including a V6 from a 79 Pontiac, a mustang II front suspension and a massive 6-3/4" rear from the same Mustang II. It seems sacriligous to not have a V8 in a Deuce coupe so I've recently purchased a fully rebuilt 68 327 275HP engine that will be going in. I'd like to run Corvette non PCV finned valve covers once I've installed the 327. What I'm wondering is if it is possible to set up the PCV system to allow me to do this? I'll be running a Edelbrock Perfromer RPM intake and a Holley 600CFM carb.

Thanks in advance.

Lots of ways to do it even without the breather hole in the rear of the block. First...make sure you don't have that hole.
You can drill breathers into the covers, get extensions that fit under the covers with holes already in them, or drill the intake to vent the fumes into the air cleaner or carb. Check out the threads on this forum for that topic. And make sure you follow them, including the deflector plates you'll have to use inside where ever you decide.

Thanks. I'll do a search. The block is not drilled for the road draft tube. I would have preferred an earlier block, but I got too good of a deal on this engine, and came with all the paperwork from the rebuild shop which is a reputable builder here.
Here is a photo of the intake. Would I be able to use the existing hole in it behind the carb? The car does not have power brakes. I really don't want to alter the valve covers or use a spacer.



Thanks again.

The existing hole behind the carb is a vacuum source not a breather port. You can use that vacuum source for your PCV setup but most use the vacuum port at the base of the carb. If you do use that vacuum source you may experience plug fouling in the two cylinders that intake runner serves, depends on a lot of factors.

you're biggest problem is that you are going to have to have TWO 'penetrations' into the engine; one to draw fumes out to the PCV and one to allow air to be drawn into the engine. if you only pull out you will be pulling (at least trying to...) a vacuum inside the engine and that will wreak havoc as the air has to come from somewhere... gaskets/seals/etc.

normally you could pull fumes in or out from the oil filler tube, but you manifold doesn't have one; and still it would only be one 'penetration.

your best solution would be to get the valve cover spacer with holes, this would allow you to draw air in one side of the engine and out the other. BUT then you have to make sure there is some baffle arrangement to separate out oil vapors/droplets.

Another solution is to use the '68/later aluminum finned valve covers. The two holes you need are included with these covers.

like these. they are available without and without the oil filler cap, BUT you have to have some way of putting oil in so the cap would be more convenient but you could pour it into the PCV hole.

I've got a brand new set of those I had bought for the Cameo I have. They aren't quite the look I was going after but they may have to do.
Lot's of good information in prior threads though!

Thanks to all.

To me, the later covers are the best/cleanest way to solve your problems including adding oil. I had forgotten about that.

The 327 I bought has an oil fill tube.

Pictures PLEASE!!!

I was wondering what was taking so long.

Car in the early 70's when he purchased it.



Car the day I purchased it........ with some god awful T-bird hubcaps and other nik-naks needing removal.



.... and on the week-end with a few changes and some temporary more period correct hubcaps.



I've purchased an 11" 5 bolt front brake kit for the Mustang II front end and a '57 Ford 9" for the rear. Once those are in, the car will be getting steel wheels with '57 Ford dog dish caps. 15" on the rear, 14" on the front.

If posting these photos warrants moving this to the off topic thread, please do.

........ but maybe this will get it back on topic

MikeM

Yeah, that's great but when you put the Edelbrock intake on it, you won't have an oil fill tube on the engine any longer.

Al T

D'oh!

You are looking to have
Corvette valve covers
An Intake that mounts a Holley
And an intelligent way to breathe the engine.

First I hate advertising for these manufacturers, and especially Edlebrock (long story)!
For such a vintage ride, that is the last thing I like to see is all of the cast in advertising logos and such! For me the performer which is a dog anyways (provides nothing more than the stock GM units will give you), so that would have to go!

I would stick with a factory dual plane and keep the oil filler tube for a proper vintage correct engine.

And then you can mimic the early 327's except you will install a breather line from the oil filler as suggested, since you don't have the back of the block hole! Some of the oil filler tubes had an extension tube coming off of them! Just get one of those!

Or put a hole thru from the end of the engine galley and vent it on the ends thru the intake rails!

Al T

Great suggestion! I actually have a filler tube from a '66. Hmmmmmm

6T7L71CPE

Wow, nothing like a real Deuce Coupe! Thanks

Back on topic...
Looks like your Edelbrock is one with the oil fill tube boss, just needs to be drilled out.

TCracingCA

Because I don't like the Edlebrock advertising show!

easy solution. Don't use a pcv
