in reading thru these posts i thought to have seen where yoy can run the stock front disk /rear drum setup(master/prop valve/dist block) with rear disc brake conversion if you added a adjustable prop valve to the rear brake line. now i can't find the post .is this possible??? it would save me running a new prop valve, removing the dist block and redoing all the brake lines. thoughts???

There is already a prop valve on a 70 chevelle. The dist block is 50/50 and you have a metering valve on the front line; I'd say you're all set for a 4-wheel disc set-up.

Whatever you do, do not put 2 prop valve in series; it could do unexpected things in certain situations.
