Yes - I can point you in the direction of a Brit who has succesfully put a BMW V8 in a Cobra. His forum tag is "TonyD", and you will find him on the UK Cobra Replica Club forum which is at
http://www.cobraclub.com/
We also have people looking at putting Jag V8s and Lexus V8s into Cobras right now. The Aussies use the Lexus V8 a lot in their cars. So there is a lot of info out there about how to deal with ECUs etc.
Slick - I still think you are dead wrong, and really don't undestand where this current train of thought of yours emanated from. No problem if you personally want to go a certain route with your car, but don't denigrate the choice of others. Their choices are every bit as valid as yours. Don't for gawd sake come to the UK - most people here stick Chevy engines into their cars, it would give you a heart attack.
BTW, I don't have Kirkham, I have a Crendon, which incidentally has an accurate twin 4" tube chassis!
