I have driven a 12.2 to 1 cast iron head 360 based 410 stroker on drag week. Putting around on pump gas, sure. Step into at all and it will detonate. 7000, not something you really want. They become very needy up there and you just don’t need to go there. In order to make it do it and live, you could have built a 4” stroker that would be scary on the street and it would live forever.
