Tom, assuming you don't have to pass smog where you live, what I would
do is first convert to electronic ignition (Crane or Petronix)and open
your plug gap to 0.040". I would raise CR by taking 0.060" off the head
and have the chambers balanced, ported and polishsd. Then instal headers
and a free flow exhaust. These are relatively cheap, easy things to
do.If you want to go further, change the cam. Despite bad press, the
Strombergs actually work well, and Webers at $1200 a pop are not worth
it unless you have a full race cam, larger valves etc.You may need to go
to richer needles. Or you could move to a place at sea level and pick up
20% more power for nothing!Just my 0.02 cents. Stu
