      The performance increase of the LS383 is incredible. The top end never changed except for the head gasket thickness which increase compression to 11:1 vs 10.5:1 in the LS1. The torque increase can really be felt. The power is seamless, the 335/30/18 KDWs are look for bite as this engine will burn em up.
