16 to 18 degree's from the factory. Most customers have left it alone, unless racing. Which distributor? Thanks for your business. If you need directions, please let me know. Sometimes they were not put into the boxes.

This is what I would do. Install the distributor, get your timing tight and tach. Run the car and watch the timing for advancement. At first sign of advance record that rpm down. Then raise your rpm's up until there is no more advance then record that rpm number. Then you will know the rate of advance for those springs. At that time you can decide if you want stiffer springs or loose springs. Or if you want timing coming in earlier or later. I have done this process I bet a hundred times, it can't go wrong. And another thing. You are going to need a dial back timing light or have a balancer with marks up to 50 degrees or more or,, timing tape on your balancer for this to really work. Or not!

I left the original springs in mine and it's all in by 1800 RPM.Its perfect for a street strip car like mine, it gives you plenty of lead time to get the car moving so you don't get any low end detonation. Gus

We need to know a little more about your entire combo, engine, gear, converter etc... It all needs to work together. Gus

Okay here I go:
Carter AVS 800
Edelbrock DP4B ported dual plane intake
Ported Stealth heads with Harland Roller 1.5
Solid street roller cam @.50= 236 intake and 243 exhaust, .552 gross valve lift. Lash at .014th intake .016th exhaust
Valves 2.14" intake 1.81" exhaust
Flow rates intake .500 - 285 .550 - 289
exhaust .500 - 217 .550 - 223
400 block with stroker kit to 499 cubes, compression 11:1
3.91 rear gear with 4 speed
Msd box
3900 lbs weight
mechanical edelbrock fuel pump
stock manifolds with 2 1/2 x pipe exhaust
manifold vacuum at idle 14 inches
I hope I did not miss anything. It runs and idles like a clock.
At 1000 rpm timing is 17 degrees at 1500 rpm timing is 25 degrees, never checked when it starts to advance somewhere between 1000-1500 rpm.

I would go WOT when working with the springs. Yes there is silent ping (dont know too much about it tho). I would go lighter till you hear pinging at WOT then go back heavier till it just stops. Right now you have alot of wiggle room as you dont know how close you are to pinging & do check at WOT. You might be close & you might far away & actually be able to use much more advance (faster)
