Sweet thanks Ill ring him anyway only take a few mins.
Interestingly, take the LS6 for example. What, 10.5 compression, valve lift is something like .560" and its fully compliant. Closed loop seqeuntial electronic engine management does alot, as does keeping the cam duration in check.
Hey what are you doing with your motor and the emissions rules? Are you runing LPG? Or did ya pull a swifty and get an allready compliance plated one before the emissions rules came in?
Cheers
