I have a question to add to this? On a car with aftermarket racing discs on the front and drums on the back, what line do you install it on? Front or rear

Rear, which also answers the previous question.

Now I am even more confused than before. Strange says that in drag cars it is usually in the front and street cars on the rear line.

Todd that is the same set up I have, discs in the front and drums on back.

I installed Strange discs front and rear on my drag-only car. I was told by Strange and others to put the prop valve on the front brakes due to the small front/larger rear tire combination. Also put it before the line-loc. But I seem to remember Strange saying that if I were to use drum brakes out back, put the prop valve in the rear. The deciding factor might be if you are running skinny tires up front,in which case you may want to limit the braking power to them. If your discs are aftermarket, I would check with the manufacturer.

Same here Jamie. I bought new Strange front brakes and they told me to install it on the front. Willwood says to run it on the rear. My car had Willwoods on the front and it always seemed to have to much front brake bias. Strange also told me to run a 2 pound residual valve for the rear brake line.

something to try before you install the proportioning valve ,, if you have access to pressure gauges for brakes ,put one the front ,one on the back apply pedal pressure and read gauges ,,if its higher on the rear install on the rear ,,higher on the front maybe you don't need one or install on the front ,, my calipers are the same size on front and rear ,I put mine on the rear line gmonde
