School me, 3.79 strokers

Have you done any math on the W2 port window relating to CID and/or the rpm per sq. In. Of port window?

Yep. And the port will be undersized so I’ll have to deal with that. Depending on bore size I’ll be 393 to 401 inches. So shifting at 7200 or a bit more even if I make them rectangular they won’t have enough area.
