    Ever see an adjustable valve in just the rear brake line?

    It is in the rear line. It is so old I kind of think there will be no identifying this valve, but I can give it a shot.

    That's the problem- there is NO combination valve. Just a Home Dupa grade splitter on the front lines. Then that valve on the rear line.

    Holley pump cam help

    Yes, I am seeing this car is a bottomless pit of neglect. Not only was it probably set up all wrong, it was ignored for far too long. The only reason I was called in to help is that I ' know about old cars'. I am beginning to regret that.

    Ever see an adjustable valve in just the rear brake line?

    I can see using that valve in conjunction with a normal combination valve. But alone? So without a residual pressure valve to keep the drums partially loaded, and just that valve limiting flow to the rear brakes, that would explain why the brakes totally suck. I hate following idiots that don't...

    Ever see an adjustable valve in just the rear brake line?

    Next time I will try to get a pic. It functionally looks like this, with only a single in and out port. But the one on this car is probably 30 years old or more so it is bigger and clunkier.

    Ever see an adjustable valve in just the rear brake line?

    So how would you adjust this for a street car? Right now the pedal travel is almost to the floor, and it takes two feet to get the car to stop. I had a friend with a 1968 Firebird. He used an adjustable proportioning valve, but it used both the front and rear lines. We set it up by waiting for...

    No. Supposedly this engine only has several thousand miles on it. When it was first installed the car only went to car shows and stuff like that. Never raced or abused. Then it sat for almost 20 years. I guess it could have slipped but only a TDC test would confirm that.

    Ever see an adjustable valve in just the rear brake line?

    So this 1978 Malibu I have been beating my head against the wall with, has no combination valve. Instead, there is some sort of an adjustable valve in JUST the rear line. The brakes totally suck. It takes two feet on the pedal to stop, and the pedal travel is almost to the floor. Brakes have...

    Has anyone gutted/ plugged a proportioning valve?

    We fixed a Tahoe that had the valve on the frame. The ABS was dead so we ripped it out. I bought that GM drum/disc combination valve that hangs under the Master Cylinder. The line to the rear was shot so we just bypassed the frame mounted valve. A splitter at the rear routed the lines to each...

    Holley pump cam help

    Update: I lowered the secondary fuel bowl level. That helped a lot. But I then had to raise the primary fuel bowl level. Then we used a base idle of 1000 rpm to see what happens when you put it in DRIVE. Well, it dropped down to 450/500 rpm, stabilizing at 510. So just putting it in gear caused...

    Another thing I noticed was that no one set the secondary fuel bowl height. It looks to be very high through the window. Would that have a path to flood the carb from the secondary side?

    REGAL Powered 60/40 To Buckets To Powered Buckets?

    I may be wrong, but I think they are the same. In my case the driver side seat attached to the power base no different than any other seat. But the part of the seat that hung over the driveshaft tunnel was , well, wide. It was kind of goofy actually, but it was flat, and it cleared the tunnel...

    Running better than ever-still wound up pushing

    "The smile you send out- returns to you". Indian wisdom. I know they are making Firebird seat belts again. The prices have come down a lot too. I haven't looked for G-body belts lately but some of the vendors will make whatever you want.

    REGAL Powered 60/40 To Buckets To Powered Buckets?

    Yes, I have found most GM seats interchange very nicely. My first set was some blue velour GP 60/40 seats. The driver seat was power. I later swapped my 1977 Firebird bucket seats onto the power base. In my Bonnewagon right now I have 1994 Firebird seats, on 1995 Buick LaSabre power bases...

    That is the first I have heard of the compression, thanks for that. But it makes me wonder why when we bumped the timing to 12° it was hard to start, like it was too far advanced.
