340 with big hopes

Seeing old posts revived is fine. It's a (re) growing thread.

Here's food for thought....

Copy the 360/380hp create engine and fully port the heads.
When it comes to a cam, add 6-8*'s duration with as much lift as possible or until the head flow stalls. The 360/380 create routinely dyno's north of 400hp as delivered. Adding a ported head and a cam with the valve lift to take advantage of it should do it. Adding a few more degrees of duration will insure it.

There should not be a whole lot of thought behind this since there are many good engines to ether copy or enhance. No shame in doing a copy or enhancing what someone else did.
