Resurrected Junk
Good weather has been holding.
Regarding R & R of carburetor. Found it was jetted with a 62 and not the 52 in the specs I have. I had never taken a Holley 1 bbl apart before and managed to screw it up. It began spitting fuel out the overflow tube. The heck with it, I was going to a 4 bbl any way. So this project is now underway.
Power steering issue turned out to be a hose that had come apart at the pump. There was enough material to hold it together so it wasn't a complete split. Had to pull the pump out to get it off.
Tunes are still to come.
With the nicer weather, I was able to drive with the windows down. Uh oh. I heard a familiar noise. It wasn't as loud or offensive, but I knew it would spell trouble. It was the other axle bearing. I wanted to go BBP and disks anyway, the heck with it.
Thanks to 74Sport I was able to get a 7¼ BBP rear with the same gear ratio as the SBP unit. In the process of removing the old rear end, I broke three of the U-bolts. You can still get 'em from Mopar. They are really proud of the nuts, however.
I had wondered why you can't convert a SBP housing to BBP. The center section casting that the axle tubes are fitted to is the same width and depth on both BBP and SBP units, at least when fitted with the 2.76:1 gear ratio. For one, the axle tubes are different lengths. The BBP was ½ inch longer on each side, though the hub-to-hub distance was the same. The other is that the SBP came on /6 cars had 9" brakes (no surprise). The backing plates had 4 bolts holding each to the flange (hmmm). The BBP has 10" brakes (again, no surprise), and 5 bolts holding the backing plate to the housing flange (whoa).
On to the 4 bbl. Hope to complete before T'giving.
