Chris has his running. He was just doing the finishing touches when I was out there last. I think he is about 80% through the build, so another 80% to go.

I am a big fan of the Clevor combo....for the two very reasons you just posted!
One of our members (Dave Wharren...not sure I spelled that last name correctly, but it's close) has a Cleveland in his ERA, so I'm sure the header issue isn't insurmountable for a Clevor build/install. Check it out.
I think a great engine/transaxle combo would be an LS7 from Brian Thomson mated to the Graziano. Figure 625hp on a conservative tune. RCR sells the kit to mate the two.
