Vacuum for Power Brakes!
I am needing some suggestions on sorting out my power brakes!
Most of the stuff is from Speedway, 4 wheel GM Metric disc brakes, rears have
mechanical parking brake. Single diaphram booster with Corvette style master
cylinder.
The engine is a small block Chevy 383 stroker with a vintage Babe Erson cam
that I have some info on. The duration, 218 degrees @ .050, 104 degree lobe separation, lift .456 Int, .449 Exh.
Pretty lumpy @ Idle.
Intake manifold is Edelbrock Performer EPS with Edelbrock 650 cfm #1406.
I wonder about where to pull the vacuum for the brake booster?
Right now the vacuum is coming from the top right side of the intake manifold.
I know that the carb has a large vacuum port in the back-middle above the base
which is now plugged.
What about vacuum pumps or canisters?
The brakes willl stop the truck but just not good enough to lock them up or stop fast!
Help me out!
Thanks! Joe
