Default 374 LSX with blower 7.80 @ 181
Switched nmca racer Bob Curran from a conventional sbc to an LSX over the winter and the first time out it ran his career best and can break both ends of extreme street record.

LSX 374 cubic inches with vortech supercharger

Very impressive! Its crazy how he ran his old combo for so many years and then this new combo runs better on its first time out.
What determined the 374 CI? was in the bore/strke ratio? Heads? or the rules for the class?
