Lower vacuum vs. vacuum brakes

[Boston GN]

Thinking of swapping over to vacuum as my PM just died.
I have lower vacuum though, 10-12". Is this going to be a big problem when swapping to vacuum brakes?
If so, what are your thoughts about manual brakes. I know some here run those with the wilwood mc.

TIA

Might be a bit low. You can also use a vacuum reserve tank to help you out.

Hydroboost is also an option to consider.

2x hydroboost.

find out why the low vac.

you should have 13+ in vac,
vac brake unit will operate with 12 + in vac,
make sure check valve is good,
others suggest hydro boost, why clutter and already cluttered eng bay?
also more potential oil leaks, plus cost!
I run vac on 2 of mine, no issues at all!
only time I've seen problems on vac setup, was bad check valve, or vac leak.

X2 and MUCH cheaper to swap over! http://www.turbobuick.com/forums/br...els/257353-vacuum-brake-conversion-costs.html
