I've always thought of a hotrod as being something absent of bling or billet and a streetrod as being one that had liberal doses of either.

Of course, that only applies to the pre-49 cars. The post 49 cars could all be called hotrods or customs or street machines, but I wouldn't use the word street rod to describe a post 49 car.

Of course I realize that the a-holes at NSRA have done a lot in the last 60 days to try and change that.
