What is the difference between a 86-93 distributor and a 94-95??
I have a 94 block, but i am using a 91 A9L computer. My car will not start and i just noticed that MSD has two different distributors
model 8456 for 86-93 5.0, which i have installed right now
and then 8455 for the 94-95 5.0L engines.
Thanks

Thanks Richard. So even though i am running the A9L computer i need to change to the 94-95 distributor since i have the 94 block. Is that correct??

Yes or no. Depends on your wiring harness. The only differnce between the distributors is the location of the TFI module. 86-93 it is mounted it on the distributor. 94-95 the TFI was remote mounted. Functionally and mechanically (as far as the block/cam is concerned), they are identical. If you found a place for all the plugs then you already have the right distributor.

So,
86-93 wiring harness --> 86-93 distributor
94-95 wiring harness --> 94-95 distributor
