Point of the thread was to offer up an explanation as to what kind of "big engine" you'd want. All bore, bore x stroke, etc... And like anything else, it's more than the sum of its parts...
And for some of us size does matter
4.2>4.15>4.1![ducking](https://rennlist.com/forums/graemlins/icon107.gif)

But in the end it is what you do with it...

Designed to be capable of 8800rpm, but we need to see where it runs out of airflow. Should be in the 8200-8300 range and we figure an honest 485-495whp or so. Maybe I'll be surprised and get over 500whp on an NA engine... We'll see...
