Re: low vacuum= bad brakes
That's not enough vacuum your cheep fix is manual master cylinder. it takes around 18 in of vacuum to operate a power brake booster properly. The other option is a vacuum pump usually around $300.it's just an inherent problem with a big cam .

Re: low vacuum= bad brakes
a friend had a similar problem. Added a Summit vacuum pump and no worries. It's more $$ than the manual brakes, but personally I like stopping power. Especially with a bigger motor.

Ah...just put a dual cup master on there and the heck with power brakes...less vacuum leaks to fix in the future and cheaper to.

Re: low vacuum= bad brakes
I agree.
If you already have power steering it is really quite simple to convert to a hydroboost brake system. Even if you don't have power steering, I make everything you need for both power steering and hydroboost brakes. Go fast trucks need stop fast brakes and hydroboost will definitely stop you fast.
