I certainly took no offense whatsoever from this thread, and everyone gets to make their own choices here, but I still feel that the idea that GM parts are more reliable than Mopar parts, especially when used in Mopar cars, is a misconception. My 1967 Crown has 125,000 miles on it and it still enjoys its original alternator, air conditioning system (in its entirety save for a 2.2 pounds of Freon over the past 15 years), valve covers, etc. I replaced the original, factory-installed starter motor about 1,500 miles ago with a rebuilt identical unit. I replaced the adjustable voltage regulator with an NOS unit after a brief visit by a non-adjustable unit purchased right off the local Mopar dealer's shelf (and it hadn't been sitting there for 30 years). I still use the original distributor, never rebuilt, with points, though I'm certainly not opposed to updating this to electronic as it's seamless and does improve reliability. The original Carter AFB lets it purr like a big kitten, starts it up hot or cold within seconds, even after it's sat for two months. The heads have never been off. Mechanically (and inside its lovely cabin), it's a surprisingly original car that certainly doesn't look like it's traveled 125,000 miles. (Anyone who's seen it can attest to that.) But it's not a trailer queen... It has never been to a show or event it didn't drive to, rain or shine. No, it's not a daily driver. But of all my old cars, this is the one I'd be most likely to get in an drive any distance. It's never let me down in 15 years, and I've never had a problem finding mechanical parts, since 440s were extremely common. Sure, if I did have a breakdown far from my trusted mechanic that was beyond my roadside toolkit and capability, I'd be very unhappy having to trust it to an unknown or to a kid who only knows how to unplug and replace modules on Hondas. But an Edelbrock carb or Delco alternator wouldn't make that aspect any better. In fact, it would introduce a whole new element of mystery to the process, as any published reference material they could find would not fully apply to my car. And when I travel, my FSM goes with me, and my AAA+ and Hagerty Classic Roadside Assistance coverage do, too. It's a small price to pay for the pleasure of driving a 35-year-old car. Imperials, especially '67s, offer extreme reliability, perhaps the best of all years of postwar Imperials, and they simply run great and drive great when maintained in their original configuration. I'm not trying to persuade anyone to undo changes they've chosen to make to their cars, but to those who have original-spec cars that aren't running right, I highly recommend finding someone who knows how to set up them up as they were intended before searching for off-the-menu alternatives. One big exception: Use only Autolite plugs. Every old Mopar loves 'em. No fouling, no pinging. One other exception: 1970-71 front brakes from a Chrysler to replace the Budd dual-pistons. No one sees them. No one has trouble working on them if they should need attention. And the surrounding components (steering and suspension are as they left Jefferson Avenue in the spring of '67). Sure, there are numerous little things that are made better, or safer, or easier to maintain today than they were 35 years ago... Electronic ignition, as noted. Radial tires. Fuel lines and brake hoses. And so on. But, for example, if a correct, properly rebuilt alternator cannot reliably serve the normal needs of an Imperial in everyday use, I strongly suspect there's something else that needs to be fixed.
