Glad to see this model getting built and the Thunderbolt theme especially. Personal favorite has always been the "teardrop" style hood on Ford drag cars. I recall the drag optioned Fairlanes of '66 vintage had a single center mounted hood scoop with the opening at the leading edge. There was a '66 Fairlane kit at one time with that style hood offered and that might be something to consider. The dual hood scoops found mostly on Mercury drag cars could be another thought. Build it the way that looks best to you and what you're wanting it to look like.
