Father has a 289 semi-comp setup. Used to vintage race it back in the late 80's early 90's. Since been retired and returned to street duty, but will all the race prep (period correct) in place. It's for sale...
Blindingly fast and handles like it is on rails.
IMO, stay away from ERA. If you want a Cobra replica, Superformance is a top choice. Yes they are fiberglass, but very well done and very accurate. Can choose from any number of high performance tune engines. Had a Superformance Coupe for a while, so can personally speak for its build quality.
