Gotta a 78 stock L48 w/auto trans ?....Seems that my 78 runs quite well all things considered....choke/carb and dizzy parameters all seem to be spot on, however, I have noticed one issue and that is when I come to a complete stop there appears to be a very so slight stumble/miss as we might refer to it back in the day....Curb idle is pretty much spot on as per the decal and goes away when I accelerate and or shift into neutral......Vette would run perfect if not for that....
As usual, any and all comments, tweaks, insights etc. would be greatly appreciated..

Pinch off the vacuum hose attached to the 5-8 manifold runner and watch it smooth out. Most likely vacuum leaks causing a lean condition on those cylinders.
