Well, I have alot of friends that have them and they all love them(some putting down 450whp on a stock tranny w/ just bushings and shifter) BUT I wouldent buy one b/c all of the ones ur going to find are going to be beaten on by some young kid or something of that nature...
BUT if u can find one for REALLY cheap, u can also build the motor for pretty cheap and have a 500-550whp reliable DD
