Carb choice for a mutt motor.
This is a good starting point for a non-smog 4 bbl setup.
The Chrysler built MP magnetic pickup distributors have a similar curve. Here's one I measured.
If the curve is close to these, then its mostly a matter of trying a little more initial which will shift the whole curve up.
Unfortunately the majority of magnetic pickup distributors will be setup for earlier emissions and 2 bbl engines so without additional info its best to measure and plot.
Factory range of acceptable timing on engine with initial set at 10* 600 to 650 rpm.
