Ok, so the new motor got a cam the size of my leg, its a 510/510 and its killing my brakes, it brakes hwn im driving around, but when i park, it just wont stop, teh torque just moves the car, what can i do, its a 4 wheel disk 87 iroc, some sorta booster valve or what can i do to it....it sux....

Turn up the idle.

The problem with the cam isn't the lift; it's the duration, and when the duration occurs.

How much vacuum do you have at idle?

You could swap in an electrically assisted master from a newer car or you could try using a vacuum reservoir.

Is there such a thing? What kind of cars have them?

shouldn't be too much cam. like rb said turn up the idle. you migth want to look at a vacuum resveror too.

Stainless Steel Brakes offers an electric vacuum pump:

cut a hole in the floorboard, and stop "flinstone style"

I own that pump dankhound said something about an electric booster, like it replaced the need for a vacuum operated booster.

The first cars that come to mind are the hybrids. No vacuum when the engine is off. They were also on some cars and trucks esspecially the disiels over the years. I would start out with a vacuum reservoir and if that doesnt see to do any good look into the vacuum pump or electric assist brakes.

I just realized i forgot another alternative for power assist. Hydraulic.
