Anyone try these distributors?

So on a Stroker where you need alot more INITIAL TIMING lets say 20-24*
you would need to limit the mechanical advance to 10-14* to get 30-34* all in at lets say 22-2400RPM MAX orrrrrrrrrrr you gunna screw some stuff up...........ping ping ping, boom!

How hard would it be to modify the mechanical advance? Is it hard to do, are there marks to help you or is it done by trial and error?

Trial and error. Not hard to do. just change/combine different springs or weights to get what you need. usually just springs.

random pic off the web...

Here's what you're dealing with...you can get weights and springs from anywhere. Coils, caps, modules etc are all over the place. Set it and forget it. I use the one like this that costs a little more but has the wider cap. Poles are spaced farther apart and the coil is IN THE CAP. I feel I get more easy adjustment this way but maybe it's in my head. Eliminates the coil wire, an external box, external coil and all the wiring. Makes the bay clean. I am unsure if this hits the firewall in a bodies. I dont think so. Maybe someone else knows for sure. Only diff between the small cap and big cap is the coil is external on the small cap unit. Just as good. I like it all self-contained. Cleans everything up and fires with a good strong spark.
fits in a 2000 dakota just fine.:cheers:
