408 ignition curver advice

I read through your thread a few days ago (great info!), as I'm gettin' back into my ignition and timing curve stuff again. I'm sure you remember chatting with me about it a couple years ago, which I greatly appreciated.
Man, did life ever get busy and crazy and challenging for a good long while. I barely had any time to even drive my car, much less work on it. I caught a break this Spring to get back on some stuff with my car. I should be receiving a curve plate and springs kit from FBO Ignition tomorrow so once I get my initial and total dialed in, I'll be trying to add in some vacuum advance on top of that. I added a vacuum advance limiter screw in the side of the dizzy a couple of days ago also but it's still plugged off for right now.

I decided to cheap out with my current distributor and welded the governor slots in the distributor instead. lol I filed them to achieve only 5 at the distributor which is 10 at the crank and it worked out really good. I said cheaped out, but the FBO plate doesn't go down that far, so I really had no choice. Slant sixes don't like much more than 30-32 total and mine likes about 20-22 initial without the vacuum can attached, so I had to weld the slots. It really surprised me that it still ran fine with the vacuum can on manifold vacuum at about 40 initial. In fact, it cleaned up the idle a little more than it was. Of course, all that extra drops out on acceleration.
