i am going to be upgrading my brakes from manual drums all around to powered discs all around. i was wondering what would be better to run to help the vacuum. My motor is a 383 with a .510 lift and 240 246 duration, so i don't have a lot of vacuum. I was looking at running a vacuum canister, but then i cam across a vacuum pump. I was curious to know which would be the better choice, I was leaning towards the canister, just because its one less thing powered by the alternator. let me know what you think.
