| RE: engine balance |

Actually, it's likely the engine WAS balanced with a CJ flywheel attached, as you seem to indicate there are similar new holes on both the front and rear counterweights. This agrees with the rod modifications, and suggests there was a rebalance done...sometime in it's history.
The problem is you don't know whether the flywheel was slightly rebalanced during a prior rebuild or what the flywheels history was. It may not have been a factory balance any more than ANY well-used 30 year old flywheel might be. Also, you really don't know whether the rods and crank were rebalanced in the same motor - the parts could have come together from anywhere and never actually balanced as a system.
$300 includes disassembly, balancing, and some reassembly of components. If you supply the loose parts, it's much cheaper than that, and you'll probably reassemble your motor much better than the shop has time for.
If you're gonna go fast AND be reliable, you really do have to know your motor well. Stuff breaks when you push it, and it's nice to know enough about your motor to anticipate problems before they occur. You can't "anticipate" problems unless you have a mental view of what's going on inside the engine to begin with.
What's more expensive: Checking things carefully now or tossing out a blown motor and buying a used Saturn?
Heck, I can give a better example than that! How about: Checking things carefully now or blowing an FE engine and replacing it with a 460 crate motor?
Yeah. That hits the spot.
