I'm always impressed when someone engineers something different in a Cobra...but, the vision in my head that I have of a Cobra very much includes a V8. The power can easily be delivered/substituted by a non-V8 engine, but the sound and feel of a V8 cannot be substituted.
AFAIC, a V8 is a large part of a Cobra's soul, and it's appeal.
But it's your car so please ignore me and build what pleases you! What would I know....I put a Chevy in mine!
