I cant leave with any boost either. brakes wont hold. even with the S-10 ones. best I got out of it was a 1.54 on foot brake and I think that might have been around 2-3psi. Now I've installed a HR Parts rear sway bar and cant 60ft out of the 1.7's guess I need to do some adjusting. anyone ever fool with them?

Jason,
Here is what worked for me when using The stock brakes. I removed the factory prop valve from under the car. I tied the front brake lines together using proper adaptors and fittings > I then installed an adjustable prop valve , like those sold in Summit or jegs on the rear line.
Not only did the brakes in total make an improvement, but I could now crank up the rear bias to make those rear drums work for you. I was able to hold over 10psi on the foot brake with mid 1.4 60fts. When leaving the track tun the bias down to prevent locking the rear brakes on the street.
Once you find what settings you like , mark or count the knob turns to go from street to race set up.
