Holley/Demon Carb stumble
On the left looks like to be an unmolested primary block.
It has port for timing vacuum, low position IFRs, power valve.
On the right, not sure what it was originally.
Angle channel looks like it was enlarged (alcohol use ?)
No provision for ported vacuum, and never was.
Power valve but restriction holes are very large - again possibly alky.
IFR might be in the cross channel at the top (white arrow).
It also might be pressed in the idle upwell, under the cap.
