Block out of square

So, further background on all of this. I inherited this engine when my dad passed two years ago. He'd specced it out and gone out to talk to the builders and such. It came out of Muscle Motors in Lansing, MI, which appears/appeared to have a good reputation here and on the For B Bodies Only forums as well. They align honed it, and they were the ones that did the dyno on it, before it went out the door. It seems likely that they would only dyno themselves or with a shop that actually knows their stuff.

That said, I had talked to them about all this in the spring of 2017, and they barely, if at all, answered their phone or responded to emails. They were spending most of their time caring for their parents too. In the meantime, there are rumors that they've closed up shop completely. So.
