When good is not enough, Camshaft time again.

I can’t see the graph very well on my phone evening I blow it up but 34-35 would need to be at 7k plus for those heads.

That’s a pretty fast chamber.

If he’s under 6500 I’d think 32 total would be tops unless I’m missing g something.
Look at the plugs he posted in #189. I know it’s hard to see but don’t they look short on total to you?
