Locked timing , yes or no

[GTX JOHN]

We run MSD with the lightest (Silver) springs and
the smallest advance bushings in our fleet of cars.
Timing is in by about 21-2200 and all our stuff leaves
the line at a higher stall speed than that. We have not
found a issue with timing chattering at the RPM we run
our stuff ( not much over 7400 ).

I may lock out the Kids Super Stock for a couple runs
and see if we pick up anything in MPH next race.

I always spun the engine on a locked out car in the old
days........... then switched the ignition on after it was turning
over pretty fast. I still do on extremely high compression bracket
stuff.
