Distributor Advance Springs
I've seen some recent posts about timing advance. Is there a certain color or weight spring to achieve the right advance. On the 73 I'm working on the springs are very heavy and don't seem to move until over 3,000 rpm. Which ones should I use? Thanks, Craig

Re: Distributor Advance Springs (CF6873)
CF -
Getting the curve and advance set up right really helps the overall performance. I'm not aware of any industry standard color-coded springs - many manufacturers make advance springs, and they're all different. Likewise, distributors are a little different from one unit to the next, so the best you can do is buy a spring assortment and try out different combinations. I can also send you some info on a kit that I have that gives you a good combination of parts for this purpose : V8FastCars@msn.com

Here is a link to my review about the SVE KwikCurve Kit.

Here is a link to my discussion thread related to the installation of the kit.

I have no doubts that you could hunt down springs on your own until you came up with an improved centrifugal advance curve. You could even purchase an adjustable vacuum advance unit. Surely you could even find some hardened washers to shim up the slack in your distributor. But this could take a considerable amount of time. (Not to mention the custom ground weights)
Take my word for it, I'm a cheap ba$tard and I try to save money every where that I can but I am glad that I purchased the kit. All the needed parts are in it along with a great instruction booklet and the combination of parts are tailored for your engine not a generic one size fits all.
