I'm Involved with high end sand cars and have seen Northstar, newer Chrysler Hemi(not 426 old school) and various new technology engines tried. By far the big and small block Chevys with blowers or turbos are used. Same with boats, mostly big block Chevys and Fords. In a cobra, in my opinion, you would be best served with big block Ford. The new engines look different and somewhat cool but did not hold up well in the sand and did not put out the power needed for sand. Much more support with Big block Ford also. More builders with experience. I have had success with my twin turbo chevy Buckshot sand car and have had no problems with Shelby engine in cobra. Shelby engine is stroked and fuel injected, been in car 5 years. Also sand cars with Northstar, ect, engines do not resale as well. My opinion only fwiw. I bring up sand cars because I ran my car with guys that had these engines and my car is just ls1 with twin turbos, puts out about 700 hp and all I do is put gas in it. Sand will test your engine for sure.
