I have been to Custom Cars/Speed Fanatix a few times over the past month while buying my new BDR and have seen Reg and crew working feverishly to shoehorn the coyote inside the cobra's mouth
Believe me when I tell you that this first install has probably cost them over $50k in labor alone to accomplish but it has come out quite nicely! I was there yesterday and the BDR looked really wicked!
At the end of the day, no matter what one may think is the "proper" engine for a cobra, I personally believe they are smart for taking the time, money and trouble to accomplish this engine install at this time because sooner or later this may be a matter of survival for their company: As a business they have to get ready for tougher emissions regs which are sure to come to the USA just as they already have in Canada and Europe; for now I'll enjoy my carburated, gas guzzling, burbling, firing spitting old school V8
but if the day comes when I'm no longer allowed to use it on the street then a coyote might very well be in my cobra's dinner menu ...
