Well here is an update on progress of running a booster with a 6:1 pedal ratio.
Today I cut the bracket holding the booster to the firewall and pedal assembly. I rewelded the bracket so the booster is paralell with the firewall. The push-rod lines up with the 6:1 hole. All in all, it turned out pretty well so far. The 'but' is that the pushrod is short by about 3/8" of making all the threads in the pedal clevis. Also, the booster valve is about 1/10" inside the firewall, which I think will give me problems with the boot. Looks like I'm going to have to shim out the booster, and purchase a bolt streacher for the push rod or fabricate a new clevis.
I'd say progress, so far is good, but there are those issues to resolve.
