Got it - I thought that's what you meant, but people have different meanings for different words these days (especially with the recent Ricer craze).

There's no easy way to determine if you have a big bore kit on there. Compression test would not tell you anything useful, as compression is somewhat unrelated to displacement. Measuring your valve lift may tell you what you have, but it's somewhat difficult to get an accurate reading if you don't have the proper tools...
