I know it's a 427, but is it an AI or what. Would like to look at torque curve as well.

Look on top of the front valve cover for the engine data tag. It should be an E-Tech either a pre-CCRS or a CCRS. The ASET AI and AC engines were not available until 2002 (2003 model year). The AI only available in the Granite, LE and MR chassis. If you want performance/tune-up specs you'll need to know the engine. You might be able to find an engine data sheet online too.
