565 inches very similar to our last motor. The heads were machined by Goodwin but it is a long from his head. the head was a team effort among several people. The biggest effort was probably from Russ at Indy cylinder for modifying the core boxes. No casting no heads. Goodwin had no input in the castings, and the start of this project. Chuck, Russ, Todd, and Myself had a lot of input in this project. I believe I have supplied every set of heads that have been machined.

The old engine made 1222 hp, hopefully the new engine will make 1240!
