750 vs 850 vs 950 Holley

The bench is at the shop I used to work for.
The QFT/ProForm 1.45 main body carb wound up consisting of one of the aforementioned "fixed" China 1.75 base plates, 3310 primary blocks, and scrounged fuel bowls. So far it has ran the best of any carb to date at the 1/8th mile track. Still has some fuel curve issues to iron out. The best way to describe what its doing is the A/F is chugging back and forth about a little over half a point . Gonna try different main air bleeds next time out.
