That is a modified OEM pulley. That is a 90A alternator from a Toyota Land Cruiser. They come with a 2v pulley so I had a machine shop turn off the front pulley since I only needed a single groove V.

I just got a denso alternator and my came with that size pulley on it actually 2 groove

Thanks..

Had the Coronet trailered over to the chassis shop so they could built an exhaust system and fix some other issues for me. One of the PS lines needed to be fabricated and TIG welded together so they took care of that for me. I drove it home from the shop so that was the first drive. It drives different than it used to so it will take some time to get used to the new setup. The PS makes a huge difference in how it drives. I had a 20:1 manual box in it which was a real bear to wrestle with at low speeds but now I can easily wheel the car around a parking lot or other tight space. Had a coolant leak that I was able to fix and now it seems to be leak free. I do have one electrical gremlin in the starting circuit that I need to chase down and then it will be ready for some more road testing.

It's been an exceptionally long winter.

Yep, the project got extended by a bunch when I decided to use the Coronet engine in the Duster. That worked out great but then I had to source and build a new engine for the Coronet. Building a new engine for the Coronet allowed me to solve a bunch of lingering issues that I had with the car but the project ended up taking 2 years rather than a few months since I spent most of my time working on the Duster. Now that the Duster has been sold I was able to get back on the Coronet. Got the exhaust installed and finished up with some trim pieces and the grill. Just need to put the hood back on and tidy up a few things in the interior and I can start putting some miles on the car. I've mellowed the car out enough that it probably doesn't qualify as a street/strip car anymore. The engine made 600 hp on the dyno but with the Try Y headers and 2.5 inch exhaust and 3.23 gears it doesn't really feel that strong. Probably a 12 second car these days.

Only one way to find out. Turn them blue bottles in the trunk on and let her rip!

Those bottles have been in the trunk for 30 years and have never been hooked up. Not sure I'll ever hook them up.

It looks good. It would be interesting to put it on a chassis dyno.

I would suggest at least trying the smallest jets you have assuming its a plate kit. Is it a big shot?

Blower on a button is what i call it.

If you want to bring it down for a day or two on the chassis dyno hit me up.

I've had the car on a chassis dyno a bunch of times over the years. (Hooking it up to the chassis dyno 20 years ago was what led me to start making the various tie down hooks and plates that I make.)
The existing engine will make between 475 and 500 rwhp on the chassis dyno. The manual 5 speed helps with the chassis dyno numbers.

It's crazy to me how many people put nitrous on their car and never use it for whatever reason.

I really enjoy playing with it.

I love the fact that you kept the 5-speed. I always think of the Coronet as "Project X" of the Mopar world.

Although this may change, I am currently of the opinion that every car we own needs nitrous and cutouts. : D

x2!

And there's really nothing wrong with that.
I always thought 12s is plenty good enough to get the heart rate up/feel sporty or whatever, and roll bars aren't much fun to live with.
With the stick shift it probably pulls crazy hard from 40/50mph up, I bet it is fun to take out and pound on.

The PS makes it much easier to drive. I learned a lot from the Duster build although I don't fully understand everything I learned. The Duster was easy to drive with a factory 24:1 box. Might have been the weight of the car but it drove nice. My Coronet on the other hand was always a pain to drive with a manual box so now I'm enjoying the PS.

I'm not enjoying the 5 speed in the Coronet. I used to like driving it but now after spending a year with the full manual 727 in the Duster I'm not a fan of using a clutch pedal. I really liked how the Duster drove with the 10 inch converter and the full manual shifting. I don't think I can bring myself to put an automatic in the Coronet since it is a factory 426 4 speed car so I might end up selling it. Pass it on to someone who doesn't mind shifting gears. I've owned the car for 40 years so it might be a tough decision to make. I'll spend some more time driving it this summer and see what I decide.

40 years is a long time Andy. Keep the car. You can put an automatic in it without butchering; or if you really feel the need pick up another project car and have two.
