alfetta stock cam timing. slight boost?
I have a 1978 Alfetta GT. California street car, 2.0 liter, SPICA, stock.
The Bible book hints that one of many simple ways of mildly (mildly) increasing power is stock cam timing adjustment. The book indicates a change of +5 and -5 degrees (1.5 degree per notch), respectively, for intake and exhaust. I've also seen a Joe Benson recommedndation of +5 and -1.
Opinions welcome on what adjustment is best .... if any at all(?). (I don't want to waste my time but if I can get a handful of horsepower here, a few there, thru various adjustments, addition of inexpensive mod's, etc, would be great.)
Also, if stock cam adjustment gain is utterly nominal, at best, will 1750 cam's do much more for me (and making smog passage doable)? I've read in other posts that 1750 cams and euro cams both still allow for smog passage ... if the rest of the system is set up properly. Thanks
