Noz Posted November 18, 2011 Author Share Posted November 18, 2011 if i get cams i want the lope to be fair im sure with 280 i wont see any better performance than 272, but if the cost is no different id rather go for 280. Quote Link to comment Share on other sites More sharing options...
DARETT Posted November 18, 2011 Share Posted November 18, 2011 If your after the sound on idle, just get yur mapper to tune it so it's a lumpy idle. Other than that if you have a well specced and ported head 272's are all you need The right 272 head setup won't restrict you even at 1500whp!

Noz Posted November 24, 2011 Author Share Posted November 24, 2011 So out of interest, if the 400bhp NA that uses a 312 duration, wouldn't he be using too high a duration for the performance required? Quote Link to comment Share on other sites More sharing options...
CanisLupus Posted November 24, 2011 Share Posted November 24, 2011 NA is another book regarding Camshafts... The longer duration and more overlap is to get more Air in the Cylinder. Quote Link to comment Share on other sites More sharing options...
