Cammer Vacuum Question

[klassickars]

I am building a Cammer and plan to use an early Ford C6 transmission but have no idea how much manifold vacuum to expect for the shift modulator.  I want to avoid a manual shift valve body.  Using Pond block and heads, 11:1 compression, Comp street lift cams, original single carb intake with Holley HP.  What kind of vacuum numbers are you Cammer folks seeing out of similar builds?  Phil

What are the cam specs, and how many cubic inches?  That will play into the amount of vacuum you have.

Looking for actual numbers from running engines.  Surely someone has hooked up a vacuum gauge to a Cammer.

You can make it whatever you need it to be.  It will all depend on the engine specs and cams that are ground for you.

Manifold vacuum literally depends on a plethora of specs.
