This was an interesting experience for me.  I had not previously dyno'd
anything, ever.  I was not able to make any adjustments on the spot as I
had wanted due to a clearance issue, but I did get one good pull to use
as a baseline.  The first 3 pulls were done back to back, and afterward
we were checking the computer and the ignition reference wires had
vibrated off of the coil, so the first 3 were useless.  My right slick
was rubbing on the tailpipe with my car tied down on the dyno, so after
my 4th pull we actually had some numbers.  I wasn't able to go any
further however.

 

Both horsepower and torque were very nice smooth curves, with a max hp
of 423.1 at 5600 and 455.9 ft/lb at 4300.  Fuel curve didn't get close
to 14:1 until 4700 rpm.  It started out at 18.2:1 at 3000.  I'll take
care of this before I go back for more pulls with a different cam on the
accelerator pump.  I may have to do some jetting changes as well, but
it's pretty good in the upper range so I think the jetting is fairly
close.
