Doing away with the stock prop valve?
Alright I've decided to make my own thread about this and see what people say.
I have my new LS1 rear sitting right under my car now just needs the brake lines routed and to be bolted up. I have a few questions about the brake lines.
I'm going from stock '88 rear drum brakes to '98 (LS1) rear 12" disc brakes that had 4-channel ABS, so I have to run new lines on the actual rear-end itself as well to mate up to the 3rd gen T connector. That's no biggy.
My question lies in the brake biasing department. I knew I was going to need an adjustable prop valve, so I bought one from Summit. I'm trying to figure out a good place to locate it in my lines, and I figured right after the stock valve looked like a good place, but its going to be kind of a pain to make such short lines, and it'd look messy.
Is it possible for me to just eliminate the stock prop valve, and run lines straight from the MC to the front calipers, and then just put the adjustable valve in between the MC and the rear calipers (about where the stock valve was). I know people run straight from the MC to a line lock and then to the front brakes, so I don't see why I couldn't do this. I just wanted to make sure. I'm under the impression that the stock valve does nothing for the front brakes and only changes the pressure to the back brakes.

Nevermind answered all my own questions with one of the tech articles on this site. Can't believe I skipped over that article the first time I was looking for info..
