That`s exactly what I run and I bought it right around the corner so when it fails, I walk in and get another not wait 3-5 days..........

Anybody make the spacers to use the Moroso small block water pump or is it a fab your own deal

V belt pulleys are easy to find, several mfgs make them. If you're looking for a Denso alternator with a v belt pulley then just order one from 440Source or Mancini or anybody else who carries the kit. Or just get one from a local supplier. If you want to go to a wrecking yard then download the instructions from my website. All of the part numbers are on there.

I have run my 68 charger for 3 years with toyota alternators. I burned one up and had to buy another.

I ran an electric fuel pump, electric fan, msd, stereo, etc... and still had problems with good idle voltage. Everything would be fine until I turned on the A/C which would automatically turn on the electric fan.

At speed I was fine but not at idle.

I installed a powermaster 140 amp gm style alt. 90 at idle. Which is what I installed 4 years ago on my 67 Coronet which has a bigger mercedes electic fan and msd atomic system and fuel pump plus A/C. Never had any inkling of a voltage problem.

While the toyota alternators worked ok they were always working hard which isn't good for the life span.

Using a higher amp alternator with an easy duty cycle or load will make it last longer.

I do starters and alternators for a living (sad I know) the Toyota alternators (Denso) will out last the Delco style. Maybe you got poorly rebuilt or needed more amps then it could give. But by far the Denso will out last in it's amp range. You step a Delco up in amperage it will shorten it's life even more. The later style hair pin Denso are light years better than either, but the price reflecks it. If I was looking to put a 140 amp alternator on a hot rod and make brackets, I would use this off a John Deere, factory 140 Amp (which really charge more), much power at an idle. You can put in 1 wire regulators, use normal, GM and Ford Pulleys. If you want the advise of someone that sells thousands of starters and alternators a month, here it is

I guess I will look into those John Deere units if my gm ones go bad.

I can only guess what JD would charge for it.. Deere
doesnt have anything cheap

John Deere Number RE46608, TY6762
Denso Number 100211-6420
It comes with an 8 groove pulley, I sell for $110, $10 if you need another pulley, $20 more if you want 1 wire or 16 Volt 1 wire. Or use the part numbers to look else where.

How does that compare in physical size to the CS130 GM Unit?

And size wise to the Toyota alt

The John Deere alternator is a work horse. It’s great for street hot rods with lots of radio and power everything, will charge great at an idle. I can’t see people of saying they were burning the Toyota ones up at the track?? The Toyota if they have brackets available is a pretty good choice.

John Deere 14.04 lbs, Body Dia. 5.4”
Toyota 9.88 lbs, Body Dia. 4.5”
CS130 11.4 lbs, 5.25” (130 centimeters, it’s where it got its name)
Baby Denso 6.39 lbs, 3.75” body (little heavier in 80a mode)

The John Deere alt would be great for cruising a hot rod with many accessories. CS130 is a pretty good choice for firing your car down the strip or even street driving (sometimes have issues at idle if you try to step them up too much), lighter and economical. Baby Denso would be great for the track, I really wouldn’t recommend it for street stip. A stock one makes 35-40 amps, I have special hand windings made to make them 80 amps and would be great for the track, hand winding is expensive and it won’t have the power at the idle or durability of the others. All can be made 1 wire, or 16 volt pretty easy.

Take a look at Moroso #63815

What about the denso 100211-603 or 605

120 amp, it's a good choice

Is this a I between size case wise 60-140. I have a new reman 60 and a Mopar denso 90 when I get the new pump in will see what will fit. All I know is with the 90 my idle rpm drops a lot when the fan comes on but volts are good.

Is there a way to identify the different denso alternators?

My stock 70 Challenger alt weighs 13lbs... really not much ov a savings? I thought the Toyota ones would be lighter?

Could the 'baby' ones be that bad for the street? What if my car is running very little in terms ov options? Electric fuel pump, a stereo, heater, lights, wipers, etc... not much else.

I pay to use a website, if I were you I would just google the number on the alternator

The Baby one is like putting a big cam in your car, sure it will make power but only on the high end, at idle it won't make squat. Your car will be running off your battery until you bring it into higher RPM's. Also as you know alternators work from magnetizam. You can only magnetize something so much before it starts building heat. Putting that much power out of a small one would take a lot of magnetizam. Heat will make it less efficient (making it work even harder yet) and way more likely to burn up and fail. When your driving down the street it would be working much harder than a normal 80 amp, it will be try to make up the power your battery lost at the stop light where a normal one would have been making a charge. Great for drag cars

Damn... the idea ov losing almost 7lbs off the engine had me in fits there for a second...

Do they get smaller/lighter than the 9.88lb Toyota one?
