You can get 15W worth of resistors inside the coil, there
is plenty of room around the periphery.  Use three 5W
resistors wired in parallel.  I did this because it's what
I had laying around.  Part number is Dale RH-5 1Ohm
5W.  Three in parallel is 0.33 ohms 15W.  Replace
the steel mounting plate with a new one made from
aluminum, and rivet the resistors to the plate with
3/32 rivets.

BTW I weighed those ignition units today and I was shocked. Seven pounds total
for both.

It is absolutely great idea to use a few less power resistors to increase
total power and decrease chances to failure. I found out, most resistors
on todays US market is on low side of advertised power, so you should
use more power when you calculate resistors value. And it make more
sense to have more powerful resistors where is critical.
Nature of most resistors has the critical part - connection between resistor
it self and contact lead. Most resistors failure is because that part.
