Doc here,

If it's a stock HEI, 10 amps will be fine , maybe a bit high...

The Stock coil draws about 6 amps..so a 7.5 SLO~BLO would be good..

If it's a "HOT" or Comp coil..It can draw up to 10 amps..

To be sure, measure the resistance across the primary side and divide that by 12 volts..It will tell you exactly how much current it will draw.

Use a slo~Blow fuse, as a coil circuit can spike and blow a fast acting fuse..slo~Blow's will hang in on spikes.

An Alternator Circuit requires a Fusible link on the big red wire. ALWAYS install the fuse link at the source of the current OUTSIDE the vehicle..Fuse links work by burning up..and can melt and set interior parts on fire, and the fumes are toxic in a closed cabin.

Doc here,

For a stock 63 amp Alternator, 10 gauge wire should work just fine.

If you have one of those super duty high output alternators, you need to find the output rating and size accordingly..
