For my 66's 327, should the HEI lead to the fuse box be unfused or should I use an inline fuse? There are two spades on my fuse box that are labled ''ign-unfused''.

Ign-unfused means it is hot when the ignition is on and there is not fuse protection, so this has nothing to do with the actual ignition/hei. There are two leads/connectors on an HEI, one for the hot lead and one for the tach. The hot lead should attach to a fused connector on the fuse block. I can't remember where I connected mine, but I will check and you will definitely get some input from fellow members. You may also post this in the electrical forum, for many replies. Good luck.

What I've done is trace the original ignition wire (the one that went to the coil) all the way back to the ignition switch. I then replaced that with a 12ga wire all the way to the distributor. The factory typically used a pink colored wire for this. You need to be sure that you have a full 12 volts to the HEI.
