Re: '71 Burb "Earl" suspension

Thanks, Leon!

Brian, I've been thinking about your rear end swap to 3.07 ratio, since I'm considering the same. I think your 454 has the torque to overcome the gearing off the line and will live an easier life with lower RPMs at highway speeds. Not as good as OD, and prob won't see much in the way of mpg... But I think it would be worth the effort if not swapping transmissions. At 70mph with 255/70R15s and 3.73 gears, my 350 will be wound up to 3020 RPMs. Go to 3.07, and I'm down to 2486 RPMs.

I've also run into a snag with the CPP rear sway bar. Or, to be exact, my mechanic has. I had to leave town for a couple weeks so had to pass off the install of the rear bar. Seems as though a body mount (which isn't there on a pickup!) interfers with the installation of the rear bar. Anyone else run into this, and is there a solution? (Front is perfect and makes a HUGE improvement in handling.)

Man this stuff is fun!
