There have always been alot of vague comments about recurving a '70-78 Z's distributer for performance. The old FAQs seems to only be for triple webers, but noone ever seems to be able to supply a working one for SU's or dual carbs.

So my question is: does anyone have a definitive advance curve (when it starts, max
advance at x rpm) that works well on the street?

Get a Mallory Distributor from Victoria British, it has a good curve for all performance minded cars. And just because they recomend them for tripples doesn't mean they won't improve a dual setup. Anything is better than the stock anti-pollution curves that they come stock with.

I've heard of poor results using the Mallory (vintage points and condensor!), I prefer to use the stock electronic one.
What I may do is get MSD's variable advance box which let's you tailor the curve electronically. We'll see...
