V6 Mechanical Advance Electronic Ign Distributor?

With the Sniper system, would it be possible to use the stock style distributor and wire the pigtail into the Holley harness? I'm pretty sure the first 3.9 engines were carbureted, but I'm not sure if the distributor was electronically controlled.

The 87 used a carb. holley 6280. It was an electronic feedback carb. There is a computer on the pass. fender. The computer controls the 6280 input, (I think the power valve) and it controls timing.
The dist. is the same for 87 (carbed,) and 88-91 TBI
