You said you tuned it yourself, right ?
How much knock were you getting ?
I've had guys think knock was ok because they had forged pistons. Knock is never ok.
Every time I've logged knock I had less than .3 volts. It was originally tuned by AMS with the old motor I just touched the tune up a bit after I built this block.
