How does a distributor work on a Pontiac engine?
How does a distributor work on a Pontiac engine?
The distributor routes electrical voltage to the spark plugs at the appropriate crankshaft angle for optimal performance. Pontiac used a few different distributors in its production engines and a wide array is available on the aftermarket.
When did Pontiac stop using transistorized ignition system?
Many electronic conversion kits are available. Since the 1960s, Pontiac has used various ignition systems that were electronically triggered. Its Transistorized Ignition was eventually replaced by the Unitized Ignition System in the early 1970s.
Do you need an ignition box for a Pontiac V-8?
MSD offers a second Pro-Billet distributor for the Pontiac V-8 in its Ready-To-Run line. It includes an internal electronic control module and doesn’t require a separate ignition control box for normal operation, but it’s certainly compatible with it. A vacuum advance canister makes it an excellent choice for street applications.
When did Pontiac start using high energy ignition?
Don’t let that appearance mislead you, however. This unit functioned perfectly after a thorough cleanup and proper lubrication. General Motors introduced its high energy ignition (HEI) system in 1974 and Pontiac used it on a number of its V-8s beginning in the middle of the model year.

Is there a HEI distributor for the Pontiac V-8?
Many companies produce brand-new HEI distributors for the Pontiac V-8. A unit like this from Pertronix offers top-quality construction and internal electronics. The aftermarket unit fits and functions just like an original, and it even accepts the factory wiring.
What should the spark lead be on a Pontiac V-8?
As piston speed increases, spark timing must occur earlier in the rotation cycle and a mechanical assembly within the distributor increases spark timing. Total maximum spark lead in a naturally aspirated Pontiac V-8 is generally between 30 and 40 degrees, and that can vary with combustion chamber type, compression ratio, and fuel octane.
