Slant 6 lean burn distributor info...

Bill,

I may be able to help. If you use two ignition systems and power only the one you want, it might work. Connect the coil (-) connections together. The un-powered may not be able to pull the coil low, so the powered one controls the ignition. This is a common method used in electronics, called open collector OR-ing. A SPDT relay could be used with an adjustable Hobbs pressure switch to control the power selection. The coil will need power when either ignition is powered.

I have not tested this, but it might work with the Mopar box, and GM HEI. The mopar boxes will need ballast.

Only one of the pickups would ever be activated at any one time. I would use a Hobbs-switch activated DPDT switch to automatically switch between pickups (only ONE coil) so that below 15 PSI I'd be using the "advanced" pickup and over 15 PSI I'd be using the "retarded" pickup.

I think that's about as complicated as I need to make it.


That's with a Lean Burn (no advance mechanism of any kind) dual-pickup distributor hooked to the double-pole/double-throw Hobbs boost-activated switch, which would then go to the MSD 6-AL digital box, and then to the coil.

Any reason why this won't work?

I'm open to suggestions, naturally.:D

Thanks again for your interest and comments!
