smogger intake?
Wait a minute! The early intakes had a road draft tube venting to the atmosphere, later this was connected to intake vacuum and used a PVC, later the PVC was moved to the valve cover and the manifold no longer had the provision for the draft tube or PVC. The oil fill was moved to the valve cover at the same time. I think you should be able to reverse engineer this and eliminate the current PVC. The only advantage would be if you wanted to use the old valve covers without the oil filler and PVC. Which is really cool! Otherwise I see no advantage other than selling it at a swap meet and buying a Edelbrock or other aftermarket intake. Post the part number or a picture if you can. A bigger issue would be the port match between this manifold and the cylinder heads you plan to use.

I'm taking the 2v setup off when I replace the head gaskets,
so I'm may as well put a 4v on cause it's free. the 360 uses
d2eaa heads, The intake sits on c4aeg heads which are a tiny bit
taller in port size. My 390 has a 65 car intake that sits on
a d2ea head and a c1ae head it runs fine. It's a 360,it needs all
the help it can get.
probaly gonna run 500cfm or so with dual straight pipes,nothing
too interesting.

William is correct about the port match issues. The early intake with the larger ports won't flow as well with the D2TE-AAs as it will with the C4AE-Gs. You would be going from a large intake runner into a small cylinder head port- a less than desirable situation. Going from big to small is okay however. If you really want the old manifold, run the C4AE-G heads with it. Or consider selling the C4s to a racer and use the money to purchase an aluminum intake. There are some folks who find the C4AE-G very desirable. They have the higher exhaust ports and the large runner intakes, with a 'D' shaped chamber. But what I want to know is, why do you want to get rid of your PVC ? A PVC system doesn't hurt your horsepower at all. DF

I not trying to get rid of the pcv specifically, that's just a
byproduct of thowing on the manifold avialible to me, and if
I'm replacing a head gasket and intake gaskets I may as well
put a 4v back on instead of a 2v. Buying an aluminum intake for
a post emissions 360 beatin' motor wouldn't help much. That's something for the 371 I'll attempt to build
