Ignition timing for stock cam/heads Magnum 5.9?

I had it just like trailbeast pretty much. 15* initial, 34* 25/2600 rpm, 52 @ cruise. This works great for the street.

A strip tune is more aggressive and not really warranted for the street. It just helps burn up tires! You should not have a problem doing that now.

Re tune the carb a bit and let ok for the maximum vacuum reading possible. That will get it running crisp!

Have you guys experimented with ignition timing much?
While I have gone through nearly every nut and bolt on my Dart in terms of body, suspension and drivetrain, I have never messed with anything on my Magnum 300 crate motor beyond bolting up the headers and changing the oil.

It runs fine, doesn't seem to ping on 87...but something tells me that the ignition timing, which I've never touched is leaving something on the table.

I have a fresh distributor ready to go in this weekend...then I'll get to know my timing light and figure out if I can get any more of those (supposed) 300 horses to come out of the barn once in a while.

What has worked well for you? How much timing do these motors like? I am running a mismatched gear ratio (the 4.10 was not a great choice to match with the A904 as it turns out) so some higher rpm power would be helpful.
