I have never built an engine or done major modifications for power. So when I had the engine built for my 72 Charger I had an idea what I wanted and let my builder, ( D&J Machine & Performance Engines), pick the components. I know the owner from a non car forum. He went with this cam - Comp Cams 21-226-4, hydraulic flat tappet cam (.519/.524 w/ 1.5).
The engine does not have enough vacuum to operate the power brakes so I installed a vacuum pump. Brakes work great and the only down side is the noise of the pump and a little vibration. When the engine is running it's a non issue because you can't hear or feel anything else.
Now my question for anyone who has used a pump is should I add a vacuum canister, (I already have one), and do I tie it into the engine or keep it separate and run the brakes and any accessories separately? My thought is just keep it separate.

Never used a pump before, but I have experience with a reserve canister and big cam on a friends truck. Works great in my opinion. I have a 73 charger with 440 solid .550 cam and 13:1 compression, makes 7in vac. I run the stock booster and brakes with no canister or pump, and I think mine works great. Ive never had a stock motor so the pedal may be harder than stock but its not too hard by any means. Ive never felt like I have ran out of vac either. I would test your booster and make sure it doesnt leak and try it without a pump and see how it works. Worse case you buy a canister, best case you have a pump for sale!
A friend has a 69 camaro with vac hidaway headlights and a big cam. Headlights dont work that well but the brakes are fine. No canister or pump here either.

Installed the pump and everything works great. I have a canister as well that I will probably install at some point, just need to find a good place for it. Everything on the car has been on hold for a bit while I am working on building a place to move my shop.
