Tuning a 440 with new carb and ignition

Post by atkinsAl »

Wonder if someone can help with a newbie question on how to tune a newly rebuild engine. I’ve messed about with engines in the past but never tuned an engine from new.
I have a mopar 440 with some mild edelbrock upgrades (performer cam / heads). I’ve just run the cam in and am looking to set the engine to run properly
I also have a new 1406 edelbrock carb and MSD ready run distributor fitted as well as an innovate air fuel ratio wide band sensor.
At the weekend I was playing around with the timing and idle setting and idle mixture screws but was doing it methodically. E.g. I set the static timing, adjusted the idle, this then changes the timing and so on. Can someone give me a steer on the step by step process for setting timing and carb?

Thanks

Once you set the timing it does not change unless you advance the RPMs and that will bring the vacuum advance into play. Adjusting the idle/carb does not change the timing :)
