my advice is to join a local corvette car club,i think there are more than one in your state,a club normaly will help you look over a car with you,the c4 started out with the crossfire injection,so if it is hp that you want then go a little later ,the tune port injected engines have more oportunities to gian that extra hp for less bucks,therte are many fine examples here in australia,you should not need have the hassle of importing and converting one,the beast c4 is the ZR1,if you have the money that is the model to get.
