Re: Eliminate draft tube options
I guess I'll find out for sure tomorrow.
Here is a pic of the engine with the ill-fated magneto before it shorted out.

Re: Eliminate draft tube options
Hei requires a 10ga power wire so run a relay driven by the regular ign coil power wire. Use a good relay and know that during normal run, not normal starting, the coil gets less than 12v due to the ballast resistor.

No problem on using 10 gauge wire with a 20amp fuse inline. My plan was to connect it directly to the ignition wire off of the ignition switch (which is also 10 gauge wire). I wasn't planning on running a relay since none are showing on both the American Autowire wiring harness for a GM HEI, nor or the wiring diagram with the distributor. The same goes for the ballast resistor, none is showing for an HEI type distributor, just for a traditional distributor with an external coil.

Re: Eliminate draft tube options
No need to fret any further on how to wire and attach a GM HEI distributor. It won't fit.
It seems that the bottom of the distributor, given its width, hits the pushrod cover and won't seat fully to the cam gear and oil pump drive. I need it to seat another 1/2" further, but that is no bueno.
