1967 327 pcv

I need help routing pcv system on my 67 camaro. Couldn't find a thread on the following set up: 327 block, edelbrock performer eps intake (without oil filler neck/pcv/breather), vented valve covers, and holly 4160 600 cfm 4 barrel. Please see pics.

My best guess is to run a hose from the breather on the back of the block to a pcv valve that would replace a breather on 1 of the valve covers. ?? not sure if hose should connect to carb. air filter intake also.??

(inherited as basket case but I believe original setup had breather on block as pictured, intake with oil filler/breather/pcv, non-vented valve covers, 2 barrel carb)

Your carb should have a provision for a large vacuum hose. In the front or the rear of the carb. Remove one of the breathers in the valve cover and put the pcv there. I suggest the rear one so you can put oil in the engine easier. The grommets are not the same for pcv and breather , so you will need a new grommet. Most auto parts store will have them. You will need one for aftermarket valve covers. They usually come in pairs. Use vacuum hose instead of fuel line. It will last longer. If your provision from the carb is already being used, you can put a "Tee" in it.

Awesome, thanks... so carb vacuum port to pcv valve which is inserted into valve cover with new grommet.

What about the open breather valve off the engine block?

That needs to be capped off to keep dirt and wasps out of motor.

You are aware that the vacuum line fitting you need to use is the half inch hose that is the same as used by the power brakes if you have them. If you have power brakes the line has to cut and a plastic tee used to add the PCV to the motor.

You are not going to use the ported or unported vacuum line that is only an eighth of an inch in size. Just wanted to be clear on this.

Got it, thanks again! I will cap that other breather off. And yes that was clear to use the larger 1/2" vacuum line. There are 2 on my carb so one for power brakes and the other for PCV.

Or, if the original '67 block is installed, you should fine a hose fitting on a cap bolted to block under the distributor.
This is where you can install a length of vacuum hose and install a PCV between the block fitting and carb fitting on its base plate.
Leave the vented VC caps on and keep air filter nipple capped off.

Yes, I have the original 67 block with the fitting under the distributor. So I will connect a 1/2" vacuum line from there to the carb vacuum and add pcv inline. Thanks.
