I'm thinking of selling the XA GS and buying an XC GXL that i have seen. The XC has had a recent respray which looks imacualate in some sort of gold and is lowered, it also has a 351 Clevo and is auto. The 351 dosent have a carby and the car dose not have a RWC and is not registed. How thirsty are mild 351's? How easy is it to get 300 HP at the fly from an XC Clevo? $3500 is being asked for the XC, is this worth it?
