Unlike the many LS-swapped Scouts on the market, this build keeps the truck's IH V8 heritage intact while adding modern fuel injection and serious off-road hardware. For a buyer who wants a genuinely capable, thoughtfully fabricated vintage off-roader with authentic International power, it is a distinctive and appealing build.1975 International Harvester Scout IIBring a TrailerWhat it's worth right nowClassic.com shows stock Scout II examples averaging around $35,862, but the custom and restomod category is a different market, averaging around $72,048, with well-built, engine-swapped examples generally trading from roughly $45,000 to $85,000 and the very best LS-powered builds reaching around $100,000. Scout II values have climbed sharply as collectors have rediscovered these original SUVs, and well-executed builds sit at the top of that trend.AdvertisementAdvertisementThis build's strengths are its comprehensiveness and its quality of execution. The seller, who owns a custom metal-fabrication shop, built much of the truck's steelwork himself, and the specification is genuinely heavy-duty: Dana 60 axles, front and rear lockers, a 411-cubic-inch IH V8 with modern EFI, and a bolt-in family cage. Notably, it retains an International engine rather than a GM swap, which appeals to purists who value authenticity, and the seller sourced a period-correct 1975 IH replacement block to match the truck.1975 International Harvester Scout IIBring a TrailerGiven the comprehensive, high-quality build and the strong market for well-executed Scouts, I would call fair value roughly $55,000 to $80,000. The current $50,000 bid with six bids and four days remaining is below that and climbing, consistent with a turnkey build of this caliber, and where it lands will reflect how bidders value the authentic IH power and the fabrication quality.Condition and detailsThe build is thorough and purposeful. The original IH V8 was bored out to 411 cubic inches during a 2025 rebuild and topped with a Holley Sniper EFI system, an aluminum radiator, and an MSD ignition module, driving through a rebuilt Borg-Warner T19 four-speed manual, a twin-stick transfer case, custom driveshafts, and Dana 60 axles with 4.10:1 gears, an ARB front air locker, and a rear Detroit locker. The body was repaired and repainted in satin metallic pewter with black Rallye-style graphics, and it rides on 17-inch Method wheels with 37-inch Mickey Thompson tires over a suspension lift with Bilstein shocks and a high-steer kit. A powder-coated family roll cage, a Warn winch, Hella lamps, and a custom pistol-storage drawer round it out.1975 International Harvester Scout IIBring a TrailerFor condition, this is a fresh, comprehensively built truck, with the build completed in 2026 and only around 300 miles added since. The seller reports rust repairs were performed in 2025 before the repaint, and the odometer shows 24,000 miles on a five-digit unit that has rolled over, so true mileage is not the point on a build like this. The seller was responsive and detailed in the comments about the fabrication, noting that the powder-coated steel accessories were made in-house and designed to bolt to factory locations without cutting, and that the engine is a factory IH replacement block sourced to match the truck's year.1975 International Harvester Scout IIBring a TrailerThe diligence on a comprehensive custom build is about verifying quality and sorting. Get a pre-purchase inspection from someone familiar with vintage 4×4 builds, with attention to the quality of the fabrication, the engine build and EFI tune, and the driveline, since a build is only as good as its execution, though the seller's fabrication background and detailed documentation are encouraging. Confirm the 2025 rust repairs were thorough, understand that a freshly completed build often needs a sorting period, and verify the Washington title's "Classic" brand suits your registration needs.

View the listing here.What makes the Scout II uniqueThe International Harvester Scout II, produced from 1971 to 1980, is one of the original sport-utility vehicles, a rugged, body-on-frame 4×4 that predated and arguably helped inspire later SUVs like the K5 Blazer and the more sophisticated Broncos. International Harvester was primarily a farm-equipment maker that ventured into the recreational off-road market to challenge Jeep, and the Scout's simple, boxy, honest design has aged into something genuinely desirable, with values rising steadily as collectors rediscover it, a trend only amplified by the revival of the Scout name for a new EV brand. Its straightforward, mechanical character makes it an ideal restomod platform.1975 International Harvester Scout IIBring a TrailerThat combination of classic looks and mechanical simplicity has made the Scout II a favorite for builds, and while many owners choose GM LS or Vortec swaps for modern power, this truck's retention of an authentic International V8, upgraded and fuel-injected, sets it apart for purists who value keeping the marque's own engine under the hood. Paired with genuinely heavy-duty off-road hardware and high-quality in-house fabrication, it represents a particular vision: a Scout built to be seriously capable and durable while staying true to its International roots. For a buyer who shares that priority, this build is a distinctive alternative to the more common swapped examples.My takeThis is a comprehensively built, heavy-duty Scout II with genuine off-road capability and, notably, authentic International power rather than the usual GM swap, executed by a seller with real fabrication credentials. My fair-value call is $55,000 to $80,000, reflecting the strong market for well-built Scouts and this truck's quality and specification. I would be comfortable in that range for a build that inspects as well as it presents.AdvertisementAdvertisementThe buying advice is inspection-led, as with any custom build. Get a knowledgeable pre-purchase inspection focused on the fabrication quality, the 411-cubic-inch engine build and EFI tune, and the driveline, and confirm the 2025 rust repairs were thorough. Understand that a freshly finished build typically needs a short sorting period, and check that the Washington "Classic" title brand works for your registration. Handle those, and the current $50,000 bid is a reasonable entry into a distinctive, capable, authentically IH-powered Scout II.Disclaimer: This post is for informational purposes only.
