performance cams and power brakes
Thought I'd ask the people on here who have ms3,ms4 or cams with big duration and lift if they had any issues with not enough vacuum to operate power brakes at idle.If so how did you fix it?..vacuum pump?

I run the MS4 on a 111 and have no trouble with my power brakes. You might have to let them cool down between rounds, but thats about it.

I am deleteing the ABS this weekend and was really thinking about ditching the booster and going full manual brakes while I was at it......just relocate the pushrod to give me more leverage
