Ok, here is my deal, I have no prop valve, I sold it, yeah, I know, so back to the brake thing now, I drag race and I need brakes real soon, elky is almost ready to go out for a low 10 sec. pass with new bullet. Here is what I had in 2004, and it stopped just fine for 123mph passes.

Stock new GM calipars in front, new GM B-body rotors and tubular upper A-arms and taller rotors also, with B- body spindles, was trying to correct the GM geometry and it worked ok, but I need perfection now, much faster this elky will go so I need the best info as possible. I had the stock prop valve on it with a line lock, all that worked fine, stock lines almost everywhere, now to the rear axle, I baught and used steel braided hoses for my new Wilwood disc brakes on my 12 bolt, and all worked great there too, so, now that I have no pro valve, and I was, going to incorporate a new Wilwood prop valve(adjustable) and I have 2 lines coming from my Strange engineering master cylinder, that worked great also, I see that my Wilwood adj. prop valve has one port in, one port out, but I have two lines from the master cyl. Am I just stupid or what here? doesn't the front brake system need proportioning also along with the rear brake system??? If I hook up the front master port line to the front brakes only, run the Wilwood prop valve in series to the rear brakes, what is to stop me from locking up the front brakes at a hard push on the pedal at 135mph?????? I am just loosing it I think, and I have forgotten more than I know nowadays, but if someone could send me a memo or something on if a stock prop would work again just fine, with all other brake parts being the same as mentioned, than does anyone have one to SELL??????? I don't have time for a math & geometry class on brake systems and the bias needed if someone already has there system figured out, I will do the math later on and get it all perfect, well, close to it as possible anyway, but if this will work could someone send me a mail and let me know?????
There has to be a drag racer out there right??????????Chevelle/Elcamino racer????? big block going low 10's or high 9's @ 125+mph????

If a stock pro valve will work again, can someone sell me one????? I have cash in hand and lots of hot gas to burn in a few weeks, so any help will be appreciated bigtime.

Thanks for looking.
