Look guys, with a Cobra and its light weight and short wheel base the only safe engine for someone without performance driving experience is a one lunger Honda lawn mower engine. Detuning a 427 is not going to keep someone from spinning the rear wheels around on cold tires/pavement if they aren't experienced.

If the OP wants to keep Cobra he can't drive because of his back - which I can't believe he could ride in either - and turn it into one that his wife can drive (safely), instead of detuning the 427 he could (1) pull it out and drop a 302 in its place and keep the 427 for resale, (2) sell it and by a small block car, or (3) sell it and buy something else like he says he might do in his other topic.
