I didn't see another place on the site specific for dyno runs ... if so, this could be moved there, Thanks.
Alrighty then, here's the results of my dyno run
The numbers are:
Tq 88.37
HP 80.19
the chart is at the bottom of this post
The build is:
Stock cases
Stock bore and stroke
Stock pistons - Cylinders were ball honed only, running stock pistons and stock (but new) rings
Mik 42 carb
Pro-Force One A/C ... Think the new HD SE knock off ... flows lots of air
72cc SE Heads as delivered from HD, no porting, no polishing, no bench flow, still covered with power coating on the inside ... yuck
.030 Cometic HG
HD lifters
Riveria Taper-Lite Chromolly adjustable ez-install pushrods
The Dyno:
I don't know the make/model of the dyno machine
on the chart is says : "CF: SAE Smoothing: 3"
on the second page printout it says "SAE: 1.03"
here's the chart

The AFR:
It's running lean at WOT, going from 13.1 at 2800 and rising to 15.1 at 5800
and it's lean on the bottom, running at about 18.1 at idle and dropping to 13.1 at about 2800rpms
I plan to install one size larger main and idle jets to get it closer to 13.1 straight across the line .... what are you thoughts on this ??
