Well I spent thursday and Friday upgrading my ignition... I'm pretty happy even with my lame distributor curve I have going on. As I posted before I bought a cardone reman distributor, which i'm very pleased with. However is came with a 15* governor, but DI is so kindly swaping my 15 for one he had welded up(Very cool of him, ty DI) to about 10*.

Right now i'm set at:
3B Initial + 30mech (15L) = 33 total...
The good thing is it doesn't ping going up steep hills or anywhere for that matter, so I will leave it alone until I get the new Gov!

I can already feel the increase in power, but where I noticed the big improvement is how much better it cruises, it is so much smoother now. I didn't really expect it.

I can't wait to try:...
8-10B Initial + 20mech (10*) = 28-30 total...

I also took my points distributor a part, I really wanted to know what it was doing. The gov was marked "L11.5" and the vac pod "6.5X".
5B init(67 stock) + 23 (11.5) = 28 total.
Whats weird seams the vacuum advance is rather small??

Heres my questions, first has anyone converted a grounded(Pre-70) Alternator to a Isolated field(Post-69), I heard it possible, it looks like if you buy brushes for 70 and put them in they might work?

2nd, whats a cheap/easy source for getting lighter weight springs?

Check and find out what the ignition timing is in your cruise RPM range I would expect the "small" vacuum advance to be normal for engines before EGR came out. All my later vehicles and distributors have such EXTREME amounts of vacuum advance. Disconnecting the EGR valve causes much pinging on my slants at part throttle. As soon as I step on the throttle so the vacuum advance reduces, then the ping goes away. REMEMBER that distrubutors from emissions controlled engines are calibrated to work with the emissions controls.

Remember that the distributor parts (centrifugal weight yoke and vacuum advance arm) are marked in *camshaft* degrees; multiply the numbers by 2 to get crank degrees. So your 6.5X (or 6.5L, 6.5D, 6.5R, etc.) vacuum advance provides a maximum of 13 crankshaft degrees of advance. Craig has already done a good job explaining why the later cars have more vacuum advance. Lighter springs? Depends how light you want 'em! These aren't so easy to rob out of junkyard distributors any more; most cars in the yards nowtimes are not eligible donors. Hot rod shops frequently have pep kits consisting of six or seven different springs, but you'll have to hunt and peck -- they are not listed for Mopar applications.

The charging system update requires a '70-up regulator *and* alternator; you cannot modify the '60-'69 alternator to work with the later regulator.[/quote]
