The steel caps are only inches long the expansion is minimal, but when two metals are the length of the block the difference in expansion rates can cause problems. I'm not trying to do or repeat what they have done, We have a fairly good depth of professional race engine development. I'm not wanting to run down the hill to one cow, We are walking and going to have a go at them all. Records that is. From looking at this piston, man I hope that.
I wanted to see what's out there. We are considering doing a clean sheet head for one of these engines. But to utilize the flow numbers of a good head, the engine needs to turn 10,000 rpm.
