Sorry, the rotary tangent is probably my fault. It would have gotten dropped a long time ago had I not put the idea down. As for Chevy's flirtation with the rotary, they were also going to use it in the Vega but decided on the all aluminum Cosworth Twin-Cam 2-liter instead. The had a concept car called a Corvega that showcased the rotary. But I digress, once again.

Wow, a twin cam A series engine, now that's different! I wonder how much it would cost to make a mold off that cylinder head and make a few more??? Just a thought. Sounds like a pretty rare piece though, how is the cam chain(s) driven? Good luck getting it all to work. Nissan Motorsports still sells 7 quart aluminum oil pans, but for almost $600! Still someday it would be nice to have one, along with the Competition oil pump that is NLA. See ya later!
