Going up a steep hill or whenever I hit the throttle, my engine starts pinging. I believe it started roughly the same time I put my MSD in, so I'm going to gap the spark plugs more (already put them to .045", but I've been todl to go to .055"). I plan on retiming it, though its currenlty only set at 12 degrees BTDC. Also going to get a pertronix ignition setup and then move up to 91 octane if I need to (already running 89, which from my point of view should not be needed as it is). Any other ideas?
For reference, it has stock compression (I believe 9.5:1, unless I got lucky).
