Ward,
Congratulations on getting your Cobra all registered. As for the engine issue don't sweat it. Especially if you shold sell it to someone in another state as they aren't like this dictatorship here. But if you should blow the engine or something you can replace it with whatever engine you want. The Cobra is smog exempt because of the SPCN and I know one person who races his and he has blown two or three engines and each time has replaced them with a different one.
