"950 HP body worked to flow 840" > Huh?
90 square sounds awefully big on the jets, I run a 1050 dominator on my 496 BBC and that's what I run.
If your having an off idle stumble make sure and check your acellerator pumps, you need a good squirt as soon as you crack the throttle.
That would be the first place I'd look before I started yanking jets and plugging power valvesand stuff even though I plug my power valves, just dont get ahead of yourself, you might cause another problem before you fix the original one.
Trust me on this one >Do one thing at a time and put back what DOES NOT fix the problem.
Be prepared when you go to the track to make several adjustments, bring plenty of tools, spare carb parts and it wouldnt hurt to have a resisdent guru handy for assistance and play with it till you get it right.
Goodluck, Cp
