406 FE,,,, interesting motor. Good to hear EM is still around. It does have a good reputation.
Excalibur is also "back in business" (original molds, etc.) but now offered only as a "roller".
The thing I liked best about the Excal was it's "user friendly daily driver" thing. I drove that car EVERYWHERE, ALL the time!
I doubt that will be the case with my ERA (which is STILL awaiting shipment to Hawaii). At 12 to 1 compression and 600 horse I don't think I'll be making many "gallon of milk" runs to the store!
You can make a strong case for a replica that CAN be driven daily!
