Early A with 360/power brakes

I have a '65 Barracuda with a 360 and I once used your exact setup. I found that the booster fit well enough without touching the valve covers. Eventually I removed that vacuum booster setup in favor of a Hydroboost setup. That 8" vacuum system has a threaded, adjustable piston that slides suggestively into the master cylinder. It took me a great deal of trial-and-error to get that distance exactly correct. If it is too long, as it was in my case, the pressure put into the master cylinder disallows brake fluid to return. If that happens, you get a firm pedal but no brakes.

Here's a pic of my current Hydroboost setup. You can see that there's only a half inch of space from the flange where the booster bolts to the master cylinder. I rarely if ever pull my valve covers, so it's not an issue for me.

If you go with Hydroboost, be absolutely sure to make the modification to the small, removable valve body from your pump to reduce the pressure. I found that having the stock high pressure (I think something like 1350psi) valve setting, I could screech the car to a stop regardless of speed with just a smidge too much foot pressure. After the modification, it feels perfect. It drops the pressure down to something like 850psi. It really makes all the difference and now the brakes feel absolutely perfect. Very powerful and predictable. Here's the article:

Please ignore the inevitable comments of "you don't need power brakes" that always show up in power brake discussions. That's unhelpful, non-technical drivel.

Here's a question: what kind of brakes do you have? Disc? Drum? Size?
