Ok now that its painted and runs like a freaking animal how do I get it stopped. Power disc in front drums in rear everything seems to work well. Now that it has the wild comp cams 284 I need 2 feet on the pedal,it only has like 8-10 inches of vac. What are my options? Vacuum pump, hydroboast, or toss everything and find something 30 or 40 yrs newer? I must say even with a smaller cam the brakes really were never great.
I have a 69 as well. I have an Isky 280 mega onboard. Prior to this I rebuilt the stock brake system. This included a replacement booster and master cylinder from SSBC, all stainless lines from Mustangs Unlimited, stainless steel braided front hoses from Russell Performance, new drum/pads/hardware/cylinders in the rear, and so far it breaks better than I thought it would. I have been thinking of rear disc as well, but so far have no need. I have low vacum as well between 9 and 11. There have been times I have had to brake in front of some stop lights, the car stopped well for what it's worth. I would think if more vacum is what you really want, go with a pump. I am not sure what it is that makes my set up work, I just think it's the combination of newer parts and all. Hope this helps, best of luck. but that's my .02 worth.
Ford used tons of them throughout the 70's and 80's and they are real easy to find and install under the aprons and look stock. 67-72 T-bird and Galaxie versions (small ones) will fit right in and look stock. You could try one out before you permanently mounted it.
years ago didnt help much step on the pedal 2x and all the vacuum is spent.Only timr you can store more than 10" is when your coasting.Stop and go its useless.

Do you have an auto or a 4 spd. With the 4spd all I have to do is push in the clutch and blip it over 2200 and get my vacuum back up to 24 inches. It is still a little rough in stop and go but it does work. A pump would be better especially on an automatic equipped car.
I have a stroker small block with a fat cam that has next to no vacuum. I also have an auto trans, air conditioning and power brakes. I spent a lot of time searching for a small light vacuum pump that I could hide up under the fender. Well FOMOCO has come to our rescue. The new 6.4 diesel Super Duty has a nice little plastic vacuum pump that they mount an the right fender apron. It has a very quick recovery time and is very quiet. Because of my vacuum needs on a hot day in a slow cruise, I am in the process of mounting a pair of the pumps for even quicker delivery. The parts manager at Varsity Ford in Ann Arbor, Mich was very helpful and patient while we tried different options. I thought for sure the Escape Hybrid would have a nice small, light vacuum pump. Nope, they use Hydroboost. I bought a SSBC vacuum pump but it's huge size and weight are a joke. It would make a very nice boat anchor. Varsity keeps these pumps in stock. If you are interested call Joe Sabo at 734- 996-3660.
The part# for the pump is 7C3Z 2A451-B. The list price is $133.98 and Varsity discounted it to $105.00. I checked and they have two in stock. UPS should be cheap as they are very light and small. I would go to your local Ford dealer and look at a diesel Super Duty. They are mounted on the passenger side above the wheel in the engine compartment. I mounted two of them and vacuum tank in the fender well of my 69 Mustang. The recovery time was quick when we bench tested it. I spent a lot of time looking for a quiet pump and one that would recover very quickly and not be a boat anchor. I really believe this will be the pump of choice for hot rodders once the word is out.
