So angle milling is not against the rules?
I’d lean pretty hard towards an Indy 360-1 CNC and one of their intakes and do some hand work to them.

Do you know what the numbers were on the previous winning engine?

I like the Indy heads idea as well.

BTW, what is this angle milling thing, it’s come up a couple of times recently and I have no idea what it is?
