Anybody running the '68 4 speed 340 cam?

12 degress (BTDC) Before Top Dead Center is the factory stock setting with Mopar electronic ignition and brain box.

If you are running the Mopar HEI conversion and hotter faster E-core coil, then you need to back it down to 8 degress BTDC, and gap the plugs at .050 ths.

Stock Build 340 with the 4 speed 340 cam.
