I have an 86 Trans Am with the computer controlled quadrajet. I have a 350 block that I plan to build and eventually swap with the 305, but that is for another day. Currently, my goal is to get the car running by bypassing the computer and running an old school carb/vacuum distributor as I have seen multiple people on here do before. Please don't reply saying that I should keep the CCC and that it will run better and be more efficient- if you could only see the state of the engine bay with all its worn out wiring and melted harnesses, you might agree with me that it's too far gone at this point. I have already made up my mind that this is the route I'm going, and will eventually be swapping the motor anyway so it doesn't even matter.

I was about to order this HEI distributor:

And I'm starting to second guess myself. I've recently been reading that Pontiac and Chevy distributors rotate different directions, and the fitment for this part on Summit only lists Chevrolet. I always thought a small block was a small block, but I want to make sure I'm not ordering something that won't fit a Pontiac. Will this work for my specific application? TIA!

 

You don't have a Pontiac. Only the stickers on the outside say that. You have a "GM".

The engine is a Chevrolet, aka "corporate GM" by that time, since they were in the process of killing off all the (redundant) others. Pontiac engines were among the first to go: last of the V8 those was in 81 if memory serves.

 

Perfect, that is what I needed to know. Thank you!
