My bet is that he has a crank tiger. There is what looks like a aftermarket ignition box under he dash. I been tossing around doing that to my EXP.
how much did going coils help?
Sorry for taking so long to post an answer.
I did go to an aftermarket EFI engine management system.
I used a Haltech computer. I wanted control over fueling and spark timing.
The other option at the time was using a turbo Tbird ecu - but that would have required a fair amount of screwing around.
With a turbo, one doesn't want to make silly/unknown mistakes - melted pistons etc...
I did get an 32-1 trigger wheel that was mounted to the front damper.
I did buy a long wiring harness which certainly helped make it all work.
