73 duster brake question

Zam1787 said
I guess maybe I should specify my exact needs... my car as is.. stops just fine.. manual discs with rear drums.. I do have to apply a lot of pressure with my foot to slow it down, I'm a 230lb rugby player, leg strength is no issue at all. I have a bench seat in the car and when I need to push on the brakes the person next to me feels it to. I was thinking power brake booster would take the load off the amount of pressure needed to
Push the brakes, not necessarily make the car stop faster. If I'm wrong please tell me, I'm not offended by criticism. I have slotted rotors and I'm running 17' rims already so having the room isn't an issue either. As far as vacuum goes, I have a full electronic ignition, and I'm using fuel injection. Everything is controlled electronically so I have very little draw from vacuum as it is. My question is.. will using a vacuum brake booster/master combo take the amount of necessary pressure down, and what parts are needed to do so... thank you guys for your time

Yur right on target and
I wouldn't worry about low vacuum off boost, this mostly occurs at really really slow speeds. I have no idea how that will play out with the Procharger, but make sure you don't pressurize the booster lol.
Here's my experience;
I ran a booster on my 360 4-speed with a 292/292/108 Mopar cam in it, and it stopped great. The only time it didn't was first start of the day, and backing up. A couple of blips on the throttle (no choke), charged it up, and she was good to go.

I highly advise against trying to use the Dual-Diaphragm, they take more vacuum to do what a regular single diaphragm does. I spent a lot of time with two of those (I already had them) but was never satisfied. I next installed a used booster off a 75 Dart, and badaboom,never looked back. I mean it was already 25 years old, and just worked. I run a 15/16 bore M/C. It takes a little more pedal travel to do the work but I like the feel of it. I worked my way down from two sizes bigger. Just make sure the rear adjusters work, and keep on working. I run that silicon fluid. I installed it in 1999, and have NEVER had problems with it.
I run Big-n-Littles; I have 235/60-14s on the front with the KH 4-piston calipers, and on the back 295/50-15s on 10 x 2s drums.
I run zero proportioning; and it stops real nice. I could run even more brake on the back, but I am happy as it is. You will be amazed at the difference. Be prepared to replace the rear shoes more often! lol.
