With the Holley 800 Dp and the conteder intake. I know where to hook up the vacuum advance. The port on the pass. side of the carb...I hook my power brakes to the port out the back..Where do I hook my PVC. Im used to Edelbrock. These holleys are new to me. Any insight would be great. Thanks.

 

Tee off of the power brake line, between the engine and the check valve.

 

Thanks RB. figured Id have to do something like that.

 

Oh Riley you should know that!!!



Ron

 

yeah Ron, I knew that. I Just like to see it in writing sometimes. My 89 has been apart for sooo long now, I hope I remember where the motor goes..
If all goes well..(wich lately, hasn't happened much) I should have the motor and tranny back in this weekend. Thanks for the replies...even your s , Ron.

 

Cool, yea I guess as a helping tip - everything above the throttle plates is ported, and everything below is full vacuum.

You could even run the pcv off the intake, as long as it's not an individual runner.
If your intake is like mine (Victor Jr.) you would need to tap a port...yuk...better off 'T'ing it like 'RB83L69' said.

Personaly I run two breathers on the driver side, and did away with the pcv.

My Holley didn't have any ports, so I acualy had to tap a port on the throttle base plate for the brakes. Since it's race, and my metering blocks didn't have any ports, I locked out the vacuum advance. (who needs anything more than 5mpg just give me WOT)

this one has a port on the pass. side ..ported , for the distributor...and 1 big port out the back ( like an edelbock) For the power assist.. The manifold has a plugged hole in the back.. So if I vent both covers a PCV valve isnt needed?...Now for the heat! I did away with all of it...do I just cap off the waterpump..Mechanical. (Cant afford brackets or fans for the electric pump)and the intake where the water lines went in? Or do I just connect the intake to the pump? I'm sure I could do either ...but wich is best?..

 

Not sure if I follow you on this one, but you don't want to spin a mechanical water pump dry. It will seize up in short order.

As far as PCV, there only a couple of extremes that really need it. One; keeping an emission equipped car from expelling gases into the air, and two; I guess a top fueler that has super small rings, and awesome cylinder pressure. These top fueler also connect the line from the engine to the headers if you can believe that. The exhaust draws the gases out in short order.
Other than that, yea you can do away with PCV with the use of breathers.

In the days before PCV, Chevy had two holes in the engine that no longer exist: One in the block behind the distributor that went to the lifter valley, and one in the front of the intake manifold that also went to the lifter valley. The one in the back had a baffle to keep oil liquid from leaving the engine, and a tube on the outside called the "road draft tube" that went down along the bell housing to below the engine - the end had a slant cut to increase the "draft" effect. The one in the front was the oil fill, which had a vented cap.

The idea was that the under-car pressure was lower than the under-hood pressure, so air would be drawn in through the filler cap and out the draft tube, drawing blow-by with it. Overall the system was marginally effective, and California made me remove it and install a real PCV system on the '57.

A dual-cover-breather system will allow pressure to escape, but it will not "purge" the vapors. Also, the pressure will be higher than outside (okay, by a small amount - but still higher), whereas with PCV it is slightly lower. Lower is better.

 

But don't forget, that with PCV the gases are introduced into a fresh air/fuel mixture, there by reducing burn effiencey.

Like with everything, it's a give-take thing.

Ron

 

yep ..My 327 had the "Smog Tube"..Thanks for the input guys, I will keep the Pcv system in-tact...

 

as for the waterpump, Ron. I was refering to where the heater hoses connect to the pump and the intake..

 

Cap them off. Connecting the intake to the pump will cycle hot water back through the engine (there's already a by-pass built in the block/pump to circulate coolant before the thermostat opens).
