Is it off an N/A engine? I've not seen an N/A head before, so that might even be standard!
I have read somewhere that swirl designs in general refer to the port shape rather than the chamber shape ... can't remember where I read it though! Maybe the ports are different in the Shelby swirl head, but they recycled the old chamber shape as it fitted what was needed (?)
Yes, it's marked 83' Which is why I said it's an 83' haha. I'm not sure where it came from. Pretty sure it was stolen from Chrysler from back in the day. I don't know if it's an N/A head or a Turbo head either. It does have turbo valves in it and the fitting for the coolant feed.
Ok swirl head/fastburn head. Whatever. It's not a bathtub style chamber and the swirl/fastburn didn't come out until 86'. So....
