EDELBROCK PRO FLO 4

The instructions say to set the timing to 12*. Find 12* on the balancer for #1 cylinder. Now line up the rotor with the #1 tower on the distributor. Once you get it running you will have to verify this 12* with a timing light by “Locking “ the timing at 12* in the advanced settings on the tablet. Once verified lock down the distributor like you would any time you adjust timing then “unlock “ timing on the tablet. The computer will control it from there. You will also need to verify fuel pressure based upon the map your running.
