Hello FTE,
I have a few quick questions on locations and id's for a few things.

Cooling

a. Why does the thermostat housing (water outlet) have a nipple on it? what does it go to?

b. What is the fitting on the other side of the thermostat, jutting out of the top of the intake hook up to? and is it needed? if so, i have to buy it, and a penny saved is a penny earned.



Vacuum

a. what is the outlet circled in red coming out of the top of the carb for?



b. I've googled and come up with either answer...what type of port do i need for my vacuum advance? some say Manifold, others say ported.

c. just to make sure, i'd like a pro to inspect my pictures, and let me know if this is how to hook up my vacuum lines. (im not running pcv, just two breathers, but it's literally 30 seconds to switch it back and forth...)

 

The first photo shows the elbow for one of the heater core hoses.

The second, I believe, is a ported vacuum source although I am not familiar with that exact carburetor. Ported vacuum is correct for the distributor vacuum advance, assuming it has just one hose going to the advance canister.

PCV is correct on your picture. Some carbs have this port, and sometimes it's in the spacer. It can be taken anywhere on the manifold, but centered is best since it will send equal amounts of blowby to all cylinders.

The power brake take off is also fine, assuming that it leads to the plenum or an intake runner (vacuum source in other words).

 

Ok Great! thanks! that answered pretty much everything!

 

a. Why does the thermostat housing (water outlet) have a nipple on it? what does it go to?

There is a short elbow hose that connects from the water pump to the T stat housing . It allows water to circulate when the T stat is closed . The fitting on top of the intake is for the heater hose .

 

If I read correcly you mentioned you plan to run two breathers also, and why need the pcv? I recommend one breather and using the pcv with a good new pcv valve. This will remove the excess unburned combustion in the engine and allow it to be reburnt. THis does not harm power at all...and it will stop a nasty oily vapor from constantly forming inside the engine bay.
