   depends on cam profile.
   
   also cant run really lairy cams on std inlet manifold.
   
   need TBs to run mega mad cams.
   
   160-165bhp is a target on catcams 708s with good headwork but thats being wishful.
   
   personally dont see a point in a L/B bottom end unless running mega spec cams that need a 8.5k plus revlimit.

   not alot of point if you dont need to do it. your just spending money for the sake of it.
   
   id get a nice set of forgies in there, and then it means you have the ability to run uber wild cams and TBs at a later date.

   Yeh get some forgies in there, and some nice cams!! If your doing it youself it will save you taking the engine apart again at a later date.

   As said there is no point lightening and balancing the bottom end. There very good as standard so if your pushing it past what a stock engine can do its really time to start replacing parts.
   
   Dont forget to put money aside for mapping and a higher flow fuel pressure regulator.
