Locked advance

If you are running a carb;
a large amount of Idle advance will usually negatively affect the transfer slot fuel delivery, usually causing a tip-in sag/hesitation. But with a 4500 stall, Ima thinking you may not notice it, However, it will still create a stink in the exhaust at idle.
Briefly, I ran the 292/108 Mopar cam, that I measured at [email protected], and that was when I learned how to tune. But I was running a manual trans, so parading with 3.55s, required the idle-speed to be quite low, lol, which demanded a retarded Idle-timing. Yeah, that took me a long time to figure out.
I got her down to 550 in gear and pulling herself. Using a modified factory Mopar distributor. I get 22 degrees out of the modified Vcan, for a total available Part-Throttle Timing of
up to 12/14+22+22= 58* after 3400 rpm. Which translates to
up to 12/14+14+22= 50*@2800..Cruising at 65= 2240 in overdrive, is
up to 12/14+10+22= 46* which is not optimum, so I have a dash-mounted, dial-back, timing module with a range of 15*, that I dial up, for up to 6 more, for up to 46+6= 52*@2240
With 3.55s, 2800 in Second gear is ~33mph, and with 50* is so smooth, and the exhaust sound is so sweet, and at Part-Throttle the lil 367 pulls so hard, that around town, that is my upshift cue .
But I pulled that big cam after a few months. I ran it just long enough to be frustrated by the lack of torque at take-off, with only 3.55s. Being a dedicated DD, with lots of hiway miles; that was all I wanted to run.
The next cam (223/110), was a whole new engine.

What I'm saying is that VA is the bees knees.
