Re: Power brakes
I am planning on doing the same thing only I am going to use the GM hydraboost setup, the scout guys do this conversion all the time due to the limited space in an 80/800 with a V8. I already have a power steering pump on the 4.3 V6 and its way to hard to do away with it with that serpentine belt.
Have you thought about power steering? I was looking at the power steering setup used in the early corvetes or T-birds, it has a control valve that is moved by the draglink and a hydrauic cylinder that mounts like a steering stabilizer. I think this setup will work well with the (weak) ross steering gear.
good luck, jjc
