the engine in my 68 only makes 12" of vac, this makes brakeing a pain.
I have been thinking about hydroboost but dont know how hard it would be to install, I can get a unit from a 85 deisel k5.

has this been done and how hard was it?

I know this has been gone over before but search is down

also looking at an electric pump this one is the same as the mp one

I could just pick up a switch or a valve and be done with it

I found out about the electric pump at www.chevelles.com
