Thanks! I learned a ton during this build and am really glad I did it myself rather than handing it over to a shop.
Since I updated this thread, I pulled the engine two more times to fix the rear main. The first two rope seals got shredded after a few hundred miles, I think due to the serrations on the crank. I had the crank polished and carefully installed a BOP one piece. It's been leak free since. I have about 2,000 miles on it now.
Overall, this setup has been trouble free and a lot of fun to drive. The lifters are quiet, oil pressure is great, it starts easy and runs cool. The carb and distributor are dialed in and the converter was a great addition. There's no shortage of torque!
It's funny looking back at the last few comments. I just did a rear end swap to a Moser 12 bolt. I kept the 3.55s but went to a Truetrac. That required a new driveshaft so I stepped it up to a 3.5" with 1350s. I also installed Global West control arms out back. This combo made a surprising difference in the way the car feels and hooks up on the road. I need to take it to the track now!
I'd be lying if I said I haven't been daydreaming a little about what's next for this engine. I can't leave well enough alone. In hindsight, a set of Edelbrocks would have been a more frugal choice and given me a lot more power. Most people don't notice the setup when I pop the hood, but every once in a while I run into a Pontiac nerd like me who appreciates it.
