your timing is off which he means by detonation, dont beat on the car while this is happening, get it to a shop and have them retime the cobra to specs....they will use a timing gun

Is the noise there only when the car is cold? Modular engines known to make some noise...

Need more details...

Car year?
Engine?
Base timing if a 5.0?
Does the knock happen @ WOT at 2200 rpm or just cruising?
