You remind me how much fun it is to mod those little I'4's. You can get in there and do all sorts of things to them and get more speed, but still be able to really wring it out and enjoy it on the road, you know? Buying a car with a monster 6.2L V8 you pretty much cannot do anything to it w/o ending up with so much power you can never use it unless you run it at the track and are a very good driver. If you like to tinker to find your own power a new corvette is a bad choice.
Did you do the work yourself? My husband and I put a set of headers on a Madza 6s (with the Duratec 3.0) and dear God it was a fucking PITA.
