I'm about to put a 3.73 l/s diff on my eta. I've been told that I should also put an i cam in to rasie the rev's on the eta. But isn't there a proformance cam for an eta (Schrick?) that would do the same thing. I know that I would also need new springs and things of that sort. any advise welcome. ------------------------------ End of bmw-digest V9 #1079 **************************
