i know someones vn ss the just has a better cam and proberly a chip in it thats running 14.9 and a one off 14.5
i ran last night at the quit motorplex, kwinana, perth wa lastnight and my stock vr ss ran 15.5's-15.6's consecutively.
check ur timing and make sure its at 10deg also advance it a little say to 12deg. this will help out with the lack of low end.
yeah i should hav her serviced b4 i tried times and stuff. atleast now i'll hopefully go forward n not backwards i guess.
remove raidiator, remove water pump housing with access to cam timing chain move crank to 2deg adv use cam dial gauge to reset cam to tdc adjust timing on dizzy to 38 deg adv @ 6000 rpm 38rwkw WILL b the minimum
