  1. Hey Chris thanks for your interest bud you sound like a great guy! I think the mufflers are a 3” thrush. We come from different worlds but still have lots in common 😁 Let me know if I can help you at all with your build! Cheers!!

  2. Hey Chris looks like you and I have the same interests lol. I am also part kiwi on my moms side from what I’ve been told. Here is a video I found from 2019 not sure how great the sound will come through. The idle is around 800-1000rpm here. Once the car is in gear it sounds quite a bit more lumpy. I also have electronic cut outs installed just off the headers with the button wired under the dash for the fun factor lol. It’s crazy loud and lumpy with them open and pretty tame sounding with them closed. When we dyno tested the car we did pulls with the cutouts open and closed to see the hp difference and it made about 15hp more with them open but was deafening to say the least lol. The guy running the dyno builds, tunes and races mopar mostly and was really impressed with the power outputs of the Pontiac. He said we could definitely pull more power out of the motor if we gave it more carburetion “850 or bigger” but would lose responsiveness at lower rpm. I like it with the Holly 750 double pumper it has instant response to melt the back tires and runs great.
