How often do you have the crate engines on the dyno? They’re fairly mild (~9.2:1 comp and 450hp right?) and it wouldn’t be hard to try a steady state test at peak TQ and swing the timing around. Just to see what happens. I for one do NOT have the experience on a dyno either one of you have, but I do know one of the smartest guys I’ve ever been around on a dyno did exactly that to find the timing requirements. I’d be very interested in the results of your test.
