I thought I was going to have vacuum issues with my bracket engine with its 265-274 . 112 solid roller cam. I had all kinds of contingency plans. Researched what it would take to go with full manual Wilwood front disc brakes, priced it all out. Thought I would try stockish boosted brakes first though.
I bought a electric vacuum pump, the kind that come on modern GM cars . 2 different types. Made custom mounting brackets, bought one way valves ect. Bought a 9" duel booster too. From E Bay and I got in a hurry and did not check if the seller accepted returns for it AND the V pump, (never make that mistake again!)
Well, the 9" booster was slightly too big to clear. So I had a 7" duel booster I booster I bought from a member years ago that I was "sure" it was too small and would not work properly. But it was a quality American made unit that was the kind that made your master cylinder level. Dug it out of the shed and put it on without any electric V pump. Bought a generic aluminum master cylinder from Speedway, 1" bore with SS sleeve, a nice adjustable proportioning valve, made a custom mount where it mounts to the 2 MC bolts and ends up right under it. Got some SS brake lines and made it all fit. Looks great.
It all works fine, plenty of brakes and the car is drum/drum. Over though it, over spent and lit some money on fire while I was at it. The 265 cam with duel 7" booster was plenty. If I had factory disc, even better.
