Working through some tunings bugs in the 440 as much as I can in the winter.

Had some issues with the Edelbrock that was on the car. When it was dyno'd it was pig rich and couldn't be brought down to good numbers.

I later swapped to a 3310 Holley with clear bowl plugs and a Quick fuel adjustable secondary set up and electric choke. Car runs much smoother and plugs look good.

However it occasionally had issues with popping through the carb on quick throttle stabs.

I just put in a new Firecore distributor and wires -as my old stuff was tired- Runs even smoother now with nice start ups. However anything more then 15 deg initial timing it really want to pop through the carb when revved at 15 it's not so bad. If you bring it up not as quick it'll rev to the moon with no issues.

Pretty sure I have a lean condition as everything checks out. The carb is box stock for jets and shooters so would would you reccomend?
