I've been running my 505" with a Dominator on the street.
It's always been a little rich (after putting in aftermarket metering blocks, before that it was WAY rich).
I've been playing with it a bit lately and I seem to be making large changes in jet sizes for little change in A/F.
The tuning forums suggested to start with a 85/95 jetting (with PV in front) as a baseline. I'm now at 78/88, and my A/F suggests I should still jet down further.
Other specs are:
Transfer slot restrictor: 0.055"
PV channel restrictor: 0.089"
Idle feed restrictor: 0.040"
Idle air bleed: 0.082"
Main air bleed: 0.026"

Also has a high flow 6.5 PV in the primary side.

Anyway, I thought I'd ask to see how people have their Doms jetted?
