HEI vs MSD comparison

I run an 11/1 367 with a 230* cam, and a 750DP, on the big yellow Accel Super Coil. I used to use a circa 1998 Orange box. That combo went 7200 for years. I'm a streeter and only use a rev-limiter as a safety for if I miss a shift in my A833.Accuracy is not called for. So I bought a Jacob's dial-back ignition timing module. This eventually replaced my Orange box. It's a great tool for zeroing in on creating a timing curve, and also has a dial back rev limiter in it. But I haven't missed a shift now since 2004. And it really doesn't matter much, cuz my lifter preload is only .020 and adjustable.
So, since I thought a tach might be a good idea, I finally bought a cheap one with a dial-type shift light.I set it to 7000, but I rarely get to see it, cuz, with 3.55s, 65 = 6900, in first-over,heehee.
That light is often set to 2300,(65 =2250 in overdrive) to indicate I'm speeding, kindof like a poor-mans cruise-control. It doesn't work in the US, on the Interstate, tho; Man people fly down there. On time,I was keeping up in traffic at 85, and some people kept flying by me. Since it was a 10 hour drive, I decided to follow this shiny red Corvette, giving him some lead. Man he was boogieing! I gave the old overdrive a workout that day at 2400/2500,lol. So I had to turn the little red light off, it was kindof bothering me.
