C4 hyroboost
I have a 86 C4 with a brand new engine. I went with a mild cam the max I could go without major changes. My problem is I lost a major part of my power brakes. Can I put a extra vacume canister to store more vacume or put a hyroboost system in it and where do I find a kit to do so

You could rob a hydro boost assy from a truck in the junk yard.
You can also rob an electric vacuum assist from early to mid '00's GM 1/2 tone trucks and 'Burb's. Many of them have a black, cylindrical vacuum pump mounted by the booster to help "add vacuum" in certain conditions.

Just a suggestion but if you truly have a mild cam, you should probably check all of your booster and mc components for proper operation. I have a fairly aggressive cam and don't have issues with vacuum.
