Hey all,

I am working on my project 67 fastback, it is a late model 302 in it converted to a carb setup w/ a Weind intake and holley 4 bbl 650. I didn't pull the car apart, the PO did, but I'm now trying to put it back together. I just don't know where the vacuum lines run....ideas? There seems to be a larger and smaller vacuum port on the back of the intake mani. The only accessories my car has is the P/S pump and the alternator. The transmission is a T-5 so there's no vacuum lines going to it (right?). So...are any vacuum lines running from carb to intake mani? I don't need smog gear so I figure I'll just put breather filters on the valve covers....is there a vac. line to the distributor or something like that?

Also, for you guys that have done the T-5 conversion, how do you hook up the reverse light switch?

Thanks!
Brandon

Do you have power brakes? If so one goes from the vac tree on the manifold to the booster. Do you have an Automatic? If so, one goes from the vac tree to the vac modulator. Do you have a vac advance distributer? If so, one goes from the ported vacuum on the carb to the vac canister. Do you have a PCV valve installed? If so you need to run a vac line to it from the main front or rear port on the carb. Can anybody think of anything else?

I think bishir means power brakes, not power steering. Power steering does not get vacuum.

Vacuum advance on distributor to carb vac
Power Brakes to manifold vac
Auto trans modulator to manifold vac

That's about it.

I was gonna just go with the breather caps and not run a PCV valve...any reason why I should (besides emissions?)

No power brakes or auto trans here. So I guess it is just the one carb vac. line to the distributor? Should I just plug up the mani ports? (Car was originally an auto trans....)

I like simple!

Later,
Brandon

I would run the PCV valve, otherwise you'll get nasty oily film all over your valve covers. The PCV valve sucks all that oily air into the carb base, and burns it.

Yea, just plug and go. Looks nice too.
