what to do with my 306?

I voted for Nitrous. The main reason I did so was because your compression is kind of high for boost really. It's most ideal, especially on a stock 302 block, to run your base compression at 8.5:1 for a boosted application. ~9.0:1 is ok, but it depends on the amount of HP and cylinder pressure you're going to make with the amount of boost you'll be running. The stock 302 has serious issues with block flex and head bolt strength with high cylinder pressures and HP. If it were me, based on what you built, I'd set the mill up with a 150 shot of spray with a progressive rate controller of some type and RPM switches for extra saftey (2500 / 6000).
