That thing shouldn't be detonating. 9.7:1 isn't bad. Have you check your distrib? I bet it advancing way past 28* you should be able to run that at 38* all in full at 2400. I run my 11.19:1 440 at 36*. I added a Snow Performance meth kit so I can run 93. It was about $250. If it were me I'd pull the distrib and curve it and have it welded in full around 36-38. No vac advace either.
