Can anyone tell me what my options are for upgrading the ignition on
this vehicle?

The engine is a V6, 3.9L, with a two-barrel Holley carburetor. The
existing distributor uses a Hall effect magnetic pickup.

The "vacuum transducer" on the spark control computer sprang a leak and
I have to replace the spark control computer along with it. I can get a
used one for under $50, but I thought I would look into the possibility
of getting better performance and/or mileage from an after market
ignition upgrade.

I would specifically be looking to bypass the stock spark control
computer altogether.

Any help greatly appreciated.

Thanks,
Jack
