Possibly my new high torque cam is entering the picture I just prefer not to see the knock sensor going past the green bars. The motor is new so it doesn't have any carbon on the pistons.
I only notice it starting to ping in 2nd gear pedal to the floor
and 3000 rpm and yes the distributor is curved. I agree carburetor engines (which mine is) run richer at elevation. After the hard pull I just reset the advance. Flat land and rolling hills are never a problem with 87 octane even with an aggressive initial timing setting. I can't imagine anyone needing more then 87 back east if they have 8-1 pistons.
