'70 W30 4 speed question.
 

Where is the OAI flapper vacuum source. I think it is from an intake manifold source, just not sure where. Photo would be nice. Thanks!

Yes, intake source for the vacuum. Drop the hammer and the flapper goes open. Same as mine, except a more radical cam.

Sorry, source is behind the carb.

Re: '70 W30 4 speed question.
 

Is it centered on the intake just behind the carb?

Re: '70 W30 4 speed question.
 

Yes it is.
