I can only find 300A automotive fuses but holder is rated for up to 500A this is for someone who wants to do the big three using a larger that stock alternator
( 220A)

Doesn't matter,the interior wiring/headlight wiring ,fuse box etc.,won't handle 320 amps,you must think the wiring ends at the engine or something,lol.Stick with the factory 220 fuse at most.Go back and reread my post,i just updated it.

Maybe you should go back and read all the post over then you’d be on the same page.
You must be a little bit dense,how do you think i picked up on the aftermarket alternators all reconmending upgrading the wiring,lol. You sir,make me shake my head,as you seem to be a bit stubborn to accept any advice from the guys who've done the wiring upgrade,several years ago,no less,lol.Tough to accept somebody else might know as much or more then you,lol

Alternator selection formula

(RATIO)

(In mathematics, a ratio indicates how many times one number contains another)

5.7 HEMI Crank Pulley Diameter

6.249 inches

Divided by

Alt Pulley Diameter

2.1654”

= 2.88

Engine RPM X RATIO = Alternator RPM

RATIO = 2.88 (X Engine 600 RPM) = 1,728

( alternator RPM ) 1,728 / 1800 = 1.04

minimum of 1800 RPM to generate output

Its like your keystokes are coming in at 100 mph and your mind is going 2 mph
Why are you aggravated only on the weekends?
I'm over here laughing at you,but you can think whatever you want,if it makes you sleep better,:gr_grin::happy160:.Why are you so hung up on not trying out the wiring upgrade,before spending a bunch of money on an aftermarket alternator. That to utilize properly,you need to upgrade the wiring anyways.You seem to have a burr under your saddle on taking advice from the guys that have already did the wiring upgrade.:doh2:

At this point the only problem I have is responding to your nonsense I think it maybe for the better that I ignore your posts when you choose to be disruptive.
Might be the best idea you've ever had,:Big Laugh:. You appear a bit hard headed when it comes to taking advice,:banghead:

While I'm trying to stay out of the romper room bickering, I just couldn't resist making some comments. Regardless of what size alternator you install it does NOT require you to upgrade all of the wiring on the truck. Just because the alternator is capable of producing 320 amps doesn't mean it's sending 320 amps through the entire electrical harness of the truck. The amperage flowing through the wiring will only be how much that circuit requires. If the circuit only needs 2 amps than it will only pull 2 amps regardless of the alternator size and rating. The constant is the voltage, which will always be in the 12-14 volt range and the amperage will vary based on how much is needed by that circuit. You increase the wire size in each circuit based on the power demands, and that's why items like the starter and battery leads are big cables.

LITTLE FUSE has a new type of mega fuse
for automotive 12v on battery post use for larger alternator amperage’s
but they also make stock amperage applications with uv red covers cost at this time about $28 for post clamp and holder with cover a nice alternative over OE for versatility.
Parts are available separately also.
