You can run GM TBI with lots of ignition systems, but by far the easiest is to run it with an HEI style ignition like the factory did. For Dino we needed a GM small-cap HEI distributor, which you can snag at the junkyard or get from the aftermarket. In our case junkyard parts would work, but we wanted the reliability of new parts in Dino’s ignition system. We used this PerTronix Flame-Thrower EST Distributor (right). Next to it is the PerTronix Flame-Thrower Stock Look Cast Distributor (left) that we would have used if we were keeping Dino carbureted.
