Bigger cam, power brake vacuum loss question - 09/07/14 08:46 PM
I've been thinking about replacing the stock grind cam in my 440 with something a little bigger to kick up the performance a bit. The rest of the engine is stock with no performance upgrades other than I added an electronic ignition. I don't really have much of an understanding of how cam size affects vacuum. What I would like to know is, at what point will increasing my cam size result in enough vacuum loss to influence how my power brakes will function?
