Well I know a little bit about engines. What I don't know is carbs, timing, vaccuum, also the spelling of vacuum, ummm, all that stuff. I'm in the midst of putting an engine in an 81 monte carlo. The engine bay is gutted, cleaned up and ready for paint. I took the vaccuum canister and chucked it. All those hoses coming off the carb = gonzo.

I'm buying a crate engine and bolting it up. I dont' care about emissions. That being said, what do I need under the hood for the basic set up? I'm buying a new carb and dome (non egr).

Feel free to dumb this down as you see fit and thanks in advance.

Looking for any good info on building a 383.

Cool

Well, for starters,

1. Full time vacuum for power brakes comes from the intake plenum behind and underneath the carb.
2. Full time vacuum for the automatic transmission modulator.
3. Full time vacuum for the A/C system, little hose going into the firewall on the pass side.
4. Probably would be nice to have a charcoal cannister for the fuel tank vent and connect to full time vacuum and connect the Purge to part time vacuum on the carb.
5. Ported vacuum for the distributor from the carb above the throttle plates.
6. Crankcase venting via the PCV line, this can be also where the vent line from the charcoal cannister is connected.
7. There will be another small hose coming from the firewall out to the engine. This one is for the water valve shutoff on the intake manifold and has vacuum on it when A/C is selected, which closes the valve and shuts off water flow through the heater core.

I'm sure others here will have input.......

Thanks for the reply Everett. I'm familiar with numbers 1,2, and 6.

Does anyone know of a link that would be a good read to learn vaccuuum basics 101.

Exclamation

Another tip......be sure to check with your state laws about removing the emission components from the engine compartment of your vehicle. Here in Missouri the components that were original factory equipment must still be installed on all 1968 and later model vehicles.
