There are a number of specs for the front end alignment, I was just wondering what the latest consensus was.
With the Hubler upgrade I'll be taking the Murray in for an alignment in the morning.
Somewhere I believe I read as much caster as you can get with toe and camber at zero.
Thanks

Yes I think it's Dave recommendation, yet all I could find on the net was that camber was everything.
Thanks for confirming that Gene

Bruce,
Dave actually recommends:
Toe in / out: 0 in.
Camber: 0 degrees
Caster: 5 degrees
If you put too much caster in you can run into problems with your power
steering pump. Caster actually causes the front suspension to rise and fall
when the wheel is turned left and right.
IIRC Dave noted that on his 8.1 Vortec he had problems with the power
steering pump relief valve popping at one time.

Rob M.

Bruce,
I have no idea what is obtainable with Bill's system; I Dave's modified
upper control arms and I got 5 degrees of caster. I had offset bushings in
the rear arm before I installed them and the best Tom Hampton could get was
1.9.
Double Trouble drives like it's on rails.

Did you see the pic of the angle between the upper and lower ball joint
which should be the caster. I think Bill Hubler has added a bit more
caster. IIRC last time it was aligned all they could get was about 2.5 deg.
