Re: What Junkyard veh. would have hi amp alt?

Keep an eye out for any full size, power everything car, (and now trucks)...
Taxi cabs, police cars & large farm/ industrial trucks will have large alternators.

If you want a Motorcraft Alternator, keep to the Ford, Lincoln, Mercury types.
I think all Motorcraft alternators are externally regulated still, so no monkeying around with the regulator required.

GM products will have Delco Alternators. With Delco, the larger the case, the higher output the alternator in most cases.
Nearly all Delco alternators are internally regulated, and you will have to by pass the regulator in them.

Older Chrysler/ Dodge/ Plymouth Full size cars will have the externally regulated alternators on them.
I'm thinking that all of the Chrysler alternators are externally regulated.
The larger old style Chrysler alternators make suitable candidates for a welder project.

Newer Chrysler products use the tiny Nippon Denso alternators. Although high output, they are not suitable for welders because of the very small rectifiers and heat sink area on the rectifier bridge. They over heat and die in short order.

So many cats, so few recipes...

Are any of these direct bolt in replacements? I once read that an 85 corvette alt was a perfect fit.

I hadn't heard that, maybe. I will be adding my alternator though, not swapping.
