Next question so I decided to start a new tread.. The motor I will be running has a distributor with vac advanced, My trans is a 350 turbo olds. but the distributor on the v6 didnt have that. Where do you run that vac advanced line to from the distributor. Also many people today are telling me this 350 rocket will not fit in a v6 car without completely changing everything. I find this hard to believe just wanted some imput.

The vacuum advance is connected to the carb, either ported or manifold vacuum. There are advantages of doing both ways, it's your choice.

So I can do it either or? Whats the advantages of each. By the way very very nice olds. I see the car on here and keep meaning to tell you

Thank you, basically, set your timing where you want it at the proper rpm. Then connect your vacuum to either the ported or timed vacuum port on the carb, no vacuum at idle. Or manifold vacuum, full vacuum at idle.

There are many threads on here that you can search about the plus's of ea. It has been argued back and forth for years. I prefer the timed port.

Switching it up a bit... Do you know if a 1971 starter will work on a 1972 motor? there both from a 350 rocket, just the 71 has a 1 inch copper spacer the other does not. both the same size ect.

The copper spacer is used on the high torque starters. The field windings are longer and the lug comes out closer to the end of the starter. The selenoid is the same between both styles. The high torque/regular starters will intechange.

BTW, I find using manifold vacuum to operate the vacuum advance to be more advantagous than using ported vacuum.

Whats the difference in the manifold and carb? Whats it do both ways that could make it run well?
