Wilwood Proportioning Valve Install Help

Iíd like to know what others have done in this situation. Iíve installed a Hydratech booster and Wilwood master cylinder in my í65 El Camino. The issue is that the Wilwood proportioning valve and hard lines will not fit between the master cylinder and the driverís side inner fender. The solution seems to be to ďreshapeĒ the inner fender so it clears, i.e. beat it inÖnot very cool looking. (The blue tape in the photo shows where the fender work needs to happen.) Also, switching the proportioning valve to the passengerís side of the master cylinder wonít work either. It hits the coils covers on the LS3.

Baer makes a good looking master cylinder with the proportioning valve mounted UNDER it. That would work great. But Iím trying to avoid paying for another master cylinder and valve.

Has anyone else run into this and what the heck did you do. Your input is greatly appreciated!

Re: Wilwood Proportioning Valve Install Help

Here's mine on my 65 wagon. But then, I don't have a hydroboost. You'll just have to get creative with the lines if you don't want to cut the inner fender. You could also put the valve in the line farther down the line, perhaps under the car. It's not like you'll be adjusting it every other day once you get it set where you want it.

Re: Wilwood Proportioning Valve Install Help

Good point about adjusting it only once. Creative plumbing may be the best answer!

Re: Wilwood Proportioning Valve Install Help

Make a new bracket to position the prop valve closer to the master cylinder. You will then need to make new hard lines to connect the 2 pieces. You will likely need to include loops in the hard lines as the prop valve and mc will be close to each other. Iíve had to do this with other builds. I have a hydraulic shop near by that can do this no problem. Might be a better option if youíd rather not DIY.

NorCal-SS: Thanks for the suggestion. I'll have a look and talk to my local shop. I'd rather spend my money making this work, than buying another one!
