Have a 66 442 with 400 engine. I need to find a diagram for the engine to carburetor vacuum lines. Car has 4 speed, no heat and no air.
installing 750 holley single fuel inlet.

 

So the only vacuum line is manifold vacuum to the distributor advance can.

 

So none to the carb itself?

 

Your call on if you want to use ported vs manifold vacuum for the advance. Ported comes off the port on the carb, otherwise use a manifold tap into one of the runners. Obviously power brakes comes off a runner at the back of the intake if you have PB.

 

Vacuum secondary on this. If I put a port in the intake where do I plug the other end into. Just checked and there are no lines coming from or going to the distributor.
thanks for your help.

If the car isn't stock, we can't know that unless you tell us. The OEM carb wasn't vacuum secondary. What else isn't stock? Hint: a photo goes a long way.

Yeah, but why bother? The car has no vacuum requirements other than distributor advance and PCV, which appears to be hooked up. It's totally aftermarket, so the stock ported vacuum source for advance is irrelevant. I don't know what additional info the OP expects to get or needs for this.
