350 vacuum modulator

[enjenjo]

What do you do for a vacuum modulator on a supercharged engine? Hmm?

I pulled a vacuum source under the carbs of a 6-71 blower setup.

What type of super charger setup  are we working with?

It's a 6-71 by either Hampton or BDS, it has one of each end plate. Dual 600 holleys on top.

So, I can pick up vacuum between the carbs and blower?

that is what I have done  on street applications.  Blown big and small block chevys...  t-350  and a t-400  transmittins,


hang a   vacuum gauge  on it , see what is there

BDS or B&M used to make a module that tapped under the blower and under the carb, and then gave the correct signal to the transmission.  A friend of mine had one in his 33.
