Finally have the 540 running in the Demon

This one has issues also. It won't idle because of internal or external drag on rotation. I am hoping it is as simple as putting a spacer behind the Powerbond balancer so it clears the Indy cast front cover. We already had to machine that cover some for clearance. I have .100 clearance between the vert and the flexplate so hopefully that isn't the issue.

This thing is gonna be pretty stout when I get that drag out so it will idle. Woo hoo.

Still need to take it back apart and cut the piston tops flat to drop the CR and maybe improve the quench.
