there is a 78 amper from an 85 M body which has the thin stator & would need slight fore/aft mount adjustments & someone mentioned it need the 10 dollar chebby chrome swing arm & someone mentioned that a high amp one can actually charge less at lower RPM's. No actual exp on that just a BTT for you. I'd think a std 70's square back of the highest amps available would work good as far as Mopar alts go.

I'm curious too, what is the highest output stock alternator that is a direct bolt-in?

You can get a powermaster that looks stock and is rated at 90 amps, but there around $140.00.

We run Summits chromes in ours.One in my 65 is IIRC 78 amps.They were under 100 when we bought them.Ive run mine for at least 10 years.On the 62 we just ran a solid state reg with a 65 round alt.It powerd my kids big stereo etc.Always charged good.My 65 I converted to the new style reg ald alt.Rocky

I switched over to a universal 1980's GM type altenrtor with the built in voltage regulator. It works great and if i ever need one on the road you can find them at any parts store.


I did have to custom make some brackets though.

I noticed the "Tuff Stuff" alternators with 130 Amp output, but I have never used one. Summit has them in the $215 to $239 price range with the difference being the more expensive is a one wire (internally regulated) unit?

One interesting thing I noticed is the 130 amp units are priced lower than the 100 amp units?

A 1978 Dodge Monaco w. 360 based on make/year/model will get you a premium reman at Autozone. Rated 65 amps.

Personally I would go with an all new alternator - a 75-90 amp rated Powermaster for all stock setup. I prefer new as used alternator cores - and reliability of reman units - seems poor.

It is also good idea to bypass charge wire connections in the Bulkhead connector and clean/check/tighten ammeter connections (if applicable).

When I looked on RockAuto, under that application, they offer a 114A model for only $70.
The shape however looks different? I guess it will bolt up. Anyone try this?
$200 is more than I'd like to pay for a PowerMaster or similar.

the 114A alternator will bolt up only if you use the unique to the 114A alternator bracketry. It will not bolt into the smaller capacity alternator bracketry.

Good info, you saved me from ordering wrong, thx!
So is there nothing larger than 65A that is a direct bolt-in and <$100?

I'm pretty sure the highest one listed in the 70's which it sounds like the 65 amper unit is that & that is the highest available. the 100/114 amp one with fan on the pulley is the Leece Neville beast which works good but is heavy & as said requires its own unique bracketry.

The 87 Diplomat/truck 78A unit is a direct bolt in.

mids 80s are rated as 78 amps although some of them gets up to 85 amps. These are JUST A BIT WIDER, maybe couple of mm, which makes a bit tight to fit into a big block. They also come with the smaller pulleys available.

Consider upgrade the wires up to ammeter to save ( as mentioned ) the bulkhead weakness. Althout once upgraded the alt, this could be a problem JUST on high loads demands which IS NOT NECESARILLY put by the alt allways, but cover yourself on that, in case on a batt weakness due a discharge for whatever reason.

( when money comes enough will jump to a 100 amps tuff stuff alt... or maybe 130, dunno. )

Is the one I'm using ( by now )

Run a parallel path between alt and amm throught the firewall. Then to batt.

I see posts here from guys who rebuild transmissions and engines who are scared to death of rebuilding an alternator. Rebuilding your own core assures that the cases match, the date codes are correct, the pulley is correct and the workmanship is good.
For round back get a set of bearings and this electrical kit:

http://store.alternatorparts.com/partnoho-7014.aspx

For square back, bearings and this electrical kit:

http://store.alternatorparts.com/partnoho-7015.aspx

This will get you 105 amps and a correct alternator.

On the round backs, the only tricky part is soldering the diodes in. Make sure the connections are clean and mechanically tight. If you can find some, use rosin core silver bearing solder. Regular rosin core will work but silver is better for heat tolerance.

This was the first rebuild project on my first Mopar. My 62 Valiant stumped the local mechanics in the small town I where I was going to college. When they could not fix it they recommended I convert it to a generator. I thought that was stupid and found two open diodes on the back of the alternator. I replaced them all and the brushes as well and reassembled. That was in 1966. The rebuild lasted the life of the car.

Thanks for the links. I have rebuilt alternator and a starter before, but I did not know where to get an upgrade kit?

I do have the C8313 adjustable regulator on the Charger.

JC Whitney had or used to have upgrade kits for em & I always wanted to try one of em, iirc the price was reasonable.

Doesn't the pulley need to be pulled off special and pressed back on?
