Not hard at all... I have a "mentor" in Oregon who knows 320's FAR better than I ever will... He showed me the process.No bandaids needed, but I did cuss and throw a few tools whe I got stumped by the wiring... early 320's were positive ground, and on first look, I could SWEAR that mine was...
I went trhough all the hassle of modding the dizzy, fabbing a spacer, swapping the drive end, pulling the VC, finding TDC, prepping the new EI dizzy, and it wouldn't fire.
OK, maybe I have it 180-degrees out (easy to do).
As I'm swapping the wiring around, I have a buddy over (Jason, aka rotorimp, who you remember for building the KA-T in Project Vert).
Jason peeks in and says, it's already been converted to negative ground.
He spins the dizzy back around, we throw on the cap and she fires on the first click of the key.
It's a great mod to avoid the hassles of a points-type distributor. You'll get a MUCH stronger spark, quicker starting, better mileage, cleaner running, etc, etc, etc.
