Ignition for 360 magnum

The stock style distributor and the 4 pin HEI module is all you need. The MSD would be an add on not needed to run the car. Helpful? Only in low rpm settings. AKA, start up. slow cruise, low rpm Hwy driving.

Rammer Jammerthinks there good stuff, I have nothing but piles of MSD junk that has left me stranded multiple times per box.
Ok so I am thinking I need:
1. Stock style vacuum distributor.
2. Gm 4 pin hei module
3. Coil?
I’m missing something? Rumblefish is close to the setup I was thinking. I’ve seen sketches of the above components. Also do I need a top grade distributor like an msd? My friend has been adamant on msd but everything is made in China now. I can get a $40 distributor off eBay if that works. Goes against my philosophy that you get what you pay for.
