Holley

Holley is about to do for ’72-’93 Dodge D-100 pickups what it did for ’67-’72 GM C-10 trucks, which is to raise their performance profile exponentially and make those old Dodge trucks highly sought after.

Holley

You may recall the Warlock, a special edition Dodge truck from the ’70s, along with the L’il Red Express, both prized by collectors. But as Holley noted, once they had reached that number of limited production trucks, Dodge returned to their regularly scheduled programming. It wasn’t until much later, when Dodge trucks all became Rams, that they built another hot rod hauler.

Holley

It should come as no surprise that Holley, with its vast array of performance products, has found a way to modify those ’72-’93 Dodge D100s, and has packaged them in a way that works almost effortlessly. The plan they’ve put together is deceptively simple, and it starts as they did, in finding a D100 in decent shape. The ’84 Dodge Ram D100 in Beige Sand that they chose is about as innocuous as they come, outside of a slightly lowered stance and their selection of wheels and tires. Nice, but hardly a predecessor to today’s TRX, right?

That was before they took the anemic 318 V8 out, and in its place installed a 392 from a 2015 Dodge Challenger R/T Scat Pack, with 485 HP and 475 ft/lbs of torque. The 6.4-liter Hemi and the Tremec TR6060 that came with it will fit nicely in the Dodge’s engine bay, using Hooker BHS528 Blackheart motor mounts, a BHS525 transmission cross member, 71223029HKR polyurethane transmission mount, and a BHS528 transmission adapter.

Mopar Performance’s 392 crate Hemi engine kit, part number 77072454AF, contains the power distribution center, accelerator pedal, engine wiring harness, chassis harness, sensors, and the powertrain control module (PCM) needed to connect today’s technology with that of the past. Fuel is provided by a custom sending unit with a 255 LPH 12-935 fuel pump, and a 19-390 returnless regulator, used inside a ’92-’93 Dodge fuel tank. The Tremec transmission uses a Bowler Magnum tail shaft conversion and a Hurst Blackjack 3918309 short-throw with a Hurst 5384331 Hurst shifter stick. Custom cast-iron, prototype exhaust manifolds, and replacement catalytic converters for a 2015 Dodge Challenger are used along with a Hooker Blackheart BH2356 exhaust kit that imitates the factory’s side-exit exhaust.

A later-model Dodge D-series clutch master cylinder is used with a factory replacement Hellcat dual-disk clutch and hydraulic slave cylinder, transmitting power through an Inland Empire driveshaft to the 4.10-geared, limited-slip rear axle. A set of modified Dodge B-series van control arms were used to lower the front end, with a custom-made flip kit in the rear.

Holley

All in, Holley spent roughly $17,000 on their D100, including $6,500 for the truck itself, and $5,000 for the engine and transmission. One of two trucks like this that Holley assembled to test how well all the components worked together, the other differed in that it used an automatic, and is a long bed. In the past, I took one of Holley’s C-10 trucks for a drive, and if that was any indication, the D100 will put a big smile on your face.

    Dodge Trucks. One of the most famous and respected names ever. No wonder they threw it out.

      It had to do with the bankruptcy, they wanted the trucks to be in their own divisional container should Fiat have failed and Chrysler was liquidated. Since that didn’t happen they really should affix “Dodge” to them again somehow (“Dodge” edition perhaps?).

    That’s cheap, and with a great outcome. Very nice.

    Can you find an sound engine and transmission for 5k?

    Is Holley factoring labour costs?

    New crate engines are going to much more expensive.
    I don’t know anyone into Dodges of that era unless they happen to be 4×4’s with a Cummins under the hood.
    My son did say that older vehicles that are outside the mainstream are becoming more popular for his generation because everything else is too expensive.

      Yeah $5K seems a little cheap for a good engine and trans w/o an excessive amount of miles.

      I’m pretty sure that number isn’t including labor, though if all the parts fit like they should, and you start with a good clean rust free truck, the power train should be a fairly simple bolt in affair. A couple of weekends and an evening or two for an experienced DIY’er and that is part of the fun of a truck like this building it yourself.

      Not really a Dodge guy but these are pretty nicely styled trucks. I like the earliest metal grille trucks the best though I’d take this over the quad rectangular headlight version.

        My dad had a small trucking business. He’d tow his pickup behind one of his gravel trucks out to remote job sites. He had a sheet of plywood He’d attach to the grill with baling wire to keep rocks from smashing the sh!t out of his pickup. He never had a problem. Try that with anything new.

      Soon those will be as well given more limited supply.

      That is cheap. Looking within 200 miles of my house for a engine and trans combo 6.4 with under 50k miles your looking more like 7-9k. Higher miles get closer to 5-6k. You can get a 5.7 with trans for well under 5k thou. More like 3500.
      They are starting to pick up on the collectible side. But still below the Ford and GMs. The cummins are worth the most but things like step side 4wd gas jobs, and the ramchargers are coming up too. 2wd stuff seems to be pretty cheap still thou.

      These are really easy to work on. I have helped friends with engine swaps on these back in the 90’s and lots of parts interchange with plenty of working room. I hope they don’t get to valuable I still want to find an early crew cab as a project truck

    These things were the favorite of our electric utility fleet manager back in the ’80s. Painted the nominal company shade of white before decal application, they came brand new with rust along every seam under the hood. First class quality eh, and drove like well, a truck from 1969. Ponderous. You had to give Chrysler credit for applying paint only several nanometers thick, though. Nobody else managed to make it so thin, yet evenly thin. Other than that they had zero to recommend them. My people preferred Chevs, and I had to go through hoops to end the run of sorry Dodges designed back in the ice age, and made by a company who didn’t know quality from a hole in the ground. The change to the big truck style front end in what ’93 or so seemed like a vast improvement. But they rusted like the blazes as well. Never have worked out what makes so many, mostly guys, find wonderful about driving around in these giant hunks of general uselessness. Deft handling they aren’t.

    Mr Sakurai seems only interested in rods, SEMA shows, and things not much related to cars. I miss that previous guy who drove a Cruz, Willems. At least he had some news items each day. I go to C/D for that now.

    And the abominable Lexus ad still haunts this silly place. She’s slowly sinking beneath the waves, Healey. And you get laughed at on other sites as the free trip guy without much of a clue about cars.

      I mean these were very old one of the longest generations of vehicle (other then vans) ever. But really the GM’s of the era were known for rust even more then the Dodges. Those old square bodies rusted by looking at em. The post 87 GM’s held up better thou.
      On paint you were far better off with the mexican built Dodges. The paint shop down there seemed to lay it on heavier or use something different.

      @conundrum – Dodge’s of that era never sold well in my region. The Chrysler/Dodge dealership went bankrupt several times since no one wanted their products. Everyone drove Ford or Chevy. We had 2 Ford and 2 Chevy/GM dealers.

    FYI…”restomod” is not a real word. Yay professionalism!

    I dig it but would rather put chevy power under the hood. So much easier to find and work on than dodge
