Alloy heads

NOBODY is questioning your MAD enginebuilding skills.

All I'm saying is that I have witnessed aluminum headed engines WILL tolerate more cranking compression before octane related issues start showing up. Don't muddy this up with your MAD tuning skillz. J.Rob

Seems to me you started it, got called out on your bullshit (again) and don't like it much.

What YOU should have said is YOU can't build an engine with the same CR on iron heads as aluminum. YOU can't do it so no one else can either.

My next build will be 12:1 on pump gas. Maybe 12.5:1 but I haven't had time to sort everything out yet. I expect the cranking numbers (which mean almost nothing) to be 200 plus. And it won't detonate.
