c-4 yes,no pwer brakes,and im changing over to electronic ign. the vucuum port i have has 4 ports with a lrg threaded hole at the top. maybe to add more ports?
most of the electronic ignition distributors still have a vacuum advance on them as do the ford duraspark distributors. So you need to remember which port coming from the carburetor maintains the vacuum advance, and if it is a non metered port then you will need to put in a valve that meters the vacuum so it still advances the distributor correctly.
thats going to be difficult because i got the car in pieces. maybe i can call on some of you to help me out with that as the build gets to that stage. right now the intake is at the machine shop, took it there to be cleaned, some how they forgot about it. so they are blasting it with glass for making me wait. i also replaced the 90 degree neck that supply's or recv's the rad fluid from or to the heater core. SMALL STEEPS, but im geting there.
