[COBRA427]

Jim,
It won't matter, any engine you use other than a Ford will be looked down upon by all the Cobra purists out there. Since most of our Cobras are replicas, I feel you should use whatever motor you want, regardless of whatever anyone may say or feel. Yes, putting in a Viper power plant is different and will get you a lot of attention if that's what you are looking for. Other than that, why would anyone want to put such a large and heavy motor in a Cobra when any V8 could make the same power? I'm sure parts for it are not inexpensive, and the sound of the exhaust sure is not what one expects to hear from a Cobra. I too am like you, and wanted a high tech engine. I decided to use a custom built modified LS6, which is small, lightweight all aluminum 346ci with 475hp and 480lbs torque all that plus more for about 9grand, including computer, wire harness, starter, shipping and insurance. My builder is located in Michigan, if you're interested, e-mail me and i'll give you more info. Did you see the Motor Trend piece on TV comparing the Viper and the ZO6? There was hardly any difference in performance between the two. Good luck which ever way you decide.

just my 2 cents worth
