My 2+2 came with standard brakes

The finished product will need better braking.

 

This looks like a real neat idea.

Why would you need this Clint?

 When I put the 454 in my convertible back in 2006 the brakes were terrible, too much cam caused low vacuum.   I tried a vacuum pump, but abandoned it right away as it shook the whole car.  I resorted to a vacuum cannister, which improved things but not to where they should be.

I changed cam's a couple years ago (when I planned on installing my vacuum powered cruise control) and again while better, braking still isn't what it should be.

As I got this Hydroboost for $28, I figured it might be a good starting point for an upgrade.

While I had to cut some of the lines (mainly the pressure line from the power steering pump to the Hydroboost), I have a cousin here in town that works at a hose place that can make me up whatever I need.

Did you buy a kit complete with lines? Or did you piece it together?
I've also learned the 1995 & prior hydroboost units have the 1-5/8" hole to accept the master cylinder. I measured an old master cylinder removed from one of my cars, and it matches that measurement.
