I have a few:
This one was still with the 1bbl. The end of the video is better since I got away from the engine, which is plagued with the horrible whine of the power steering pump.
This is one I did driving through town. Again, annoying sounds. This time, my low range shifter rattles (Since fixed).
One of me off-roading.
Need to get some new ones now that I've quieted down a lot of the annoying sounds.
All in all, I LOVE the way it sounds.
I have a 3-way cat, and a Dynomax turbo muffler, and I couldn't recommend the muffler enough. Smooth and quiet when at low RPMs, powerful and means business when you step on it, no drones or buzzes. Perfect.
I don't know anyone else who uses one and I'm not sure why. Got recommended to me from a guy who runs an exhaust shop and has an old Toyota Landcruiser with an I6 in it.

pretty happy with the flowmaster 40 and 2.5" all the way out, was asked once if I had a bigblock 8 under the hood
pretty quit on the freeway even at 75 mph but can make some noise if you want it to.
I found some new OEM EFI manifolds on ebay at a great price.
for the price you paid for the 390 IMO it would be well worth it to take to a shop and have it rebuilt proper. not sure where they got the carb number from tho

That makes me wonder if it is really a 390. I haven't been able to find much for those numbers as well. The oldcarmanual, I think, had those numbers listed for a carter I believe, but not everything matched, just the 3489 or whatever it is.

I found "some" info on something that was a Holley about a 3489 listing.
It might be a 370cfm, which would make sense by the numbers on the plates.
The primaries are 107s and the secondaries are 91s. I think mine are 109s and 93s or something like that. Close, but slightly bigger.

Don't know if those are actual corresponding numbers, but it's the only bit I was able to find.

I had found that same bit of info. Wasn't sure what to do with it though. I had looked at the primaries and secondaries and noticed the numbers, but wasn't confident enough in what they meant really. Looks like it's gonna be quite an adventure.
