A Cummins-Powered 2006 Chevy Trailblazer and 10 More Legit 4x4s from the 2020 Fall 4-Wheel Jamboree Nationals

The 39th Annual O’Reilly Auto Parts Fall 4-Wheel Jamboree Nationals served up a mouth-watering collection of incredible 4x4s.

One of the great things about a 4-Wheel Jamboree is that these events draw hundreds of 4x4s. This offers the opportunity to easily peruse a wide range of four-wheel-drive rigs sporting a wide range of modifications.

The three-day 39th Annual O'Reilly Auto Parts 4-Wheel Jamboree Nationals was held at the Indiana State Fairgrounds in Indianapolis, Indiana. We attended the Fall 4-Wheel Jamboree Nationals and photographed a variety of rigs that should offer something for all 4x4 fans.

Tim's 1972 Chevy K5 Blazer

Tim McCaffrey's carefully crafted 1972 Chevrolet K5 Blazer stood out from the crowd, not just because of its bright white paint, but also because of the right mix of modifications sprinkled into this full restoration project. Coming from Oswego, Illinois, Tim named his 1972 Chevy K5 Blazer "Red Rocker" as an ode to Sammy Hagar. The truck sits on a 6-inch suspension lift supported by a 10-bolt axle in the front and a 12-bolt axle in the rear, both with 3.73 gears. Power is provided by a 383 stroker, sent through a built TH350 three-speed automatic transmission mated to a NP 205 transfer case, which gets the 35x12.50R18 tires turning with ease. Other unique features of this rig include a custom fabricated rollbar.

Jim's 1966 Ford Bronco

Jim Fugit of Shelbyville, Indiana, built a 1966 Ford Bronco that could hang with hot rods on the strip and stalk Jeeps on the trail. This Bronco is powered by a small-block Ford 351 Windsor V-8 with GT40 heads and a hearty 0.512 lift camshaft with 110 degree lobe separation angle, topped off with a Shelby Cobra intake. A front Dana 44 and rear Ford 9-inch support the truck. Skyjacker Softride leaf springs provide 4.5 inches of lift to free up room in the wheel wells for the 33x11.50R17 tires.

Justin's 1972 GMC K10

Justin St. John of Indianapolis, Indiana, conducted a full frame-off restoration of his 1972 GMC K10. All of the original body parts were able to be fully restored and maintained, making this an all-original matching-numbers truck, minus the 4-inch suspension lift. The original drivetrain was also retained and refreshed and includes a small-block 350ci V-8 mated to a TH350 automatic transmission and NP205 transfer case. The factory 10-bolt front axle and 12-bolt rear axle with 4.10 gears turn 35x12.50R15 tires.

Rick's 1988 Ford F-350

Rick Legrow of Centereach, New York, has been a regular at the 4-Wheel Jamboree Nationals for many years. His 1988 F-350 "Longfoot" serves as a tribute truck to America's military. Powered by 514ci stroker capable of making 626 hp and 837 lb-ft of torque combined with 5.38 gears in the front Dana 60 and rear GM 14-bolt, this big-rig has no problem turning the beefy 54-inch tires. The rig uses a combo of coilover remote-reservoir shocks, plus remote-reservoir bypass shocks on all four corners. It's also worth mentioning that the 10,000-watt stereo system packs a serious punch. The truck tells the story of America's modern military history through beautifully detailed airbrush illustrations starting with WWI and continuing all the way to the Global War on Terrorism. Rick had the countless hours of airbrush work started in 1990 and has continued to add to it throughout the years to honor the men and women of America's military.

Mark's 1978 Toyota FJ40

Mark Bristow of Indianapolis, Indiana, brought two FJ40s to the 39th Annual O'Reilly Auto Parts Fall 4-Wheel Jamboree Nationals. Mark's pair of Land Cruisers stood out from the crowd for very different reasons. His bone-stock 1978 Toyota FJ40 was actually his daily driver when he was 16 years old. But this FJ40 hasn't been in his possession the entire time. Not knowing any better at the time, Mark sold the Toyota FJ40 to the Indianapolis Zoo and almost instantly regretted selling it. Mark always kept tabs on his old Cruiser and when the Indianapolis Zoo decided it was time to sell it Mark got right of first refusal. Without hesitation Mark bought back his old FJ40. The old rig had sat idle for years, but with some basic TLC on the fuel system and new tires it was back on the road in no time. Everything is stock, and Mark has no plans of changing that.

Mark's 1974 Toyota FJ40

Mark's 1974 Toyota FJ40 is a totally different animal in comparison to his bone-stock Project Elephant 1978 Toyota FJ40. Mark went full custom restoration with this old Cruiser and took no shortcuts along the way. The entire truck to include the body and frame have been powdercoated, and all the badges, hinges, and lights are genuine Toyota. Mark stuffed an Isuzu 4BDT11 turbodiesel between the framerails. Exhaust is routed through a 3-inch downpipe that runs into a 4-inch straight pipe and finally into a 5-inch exhaust tip, all stainless steel. The suspension on the truck is also unique as it consists of a spring-over-axle configuration with custom shackles, King shocks, and stabilizer. Wilwood disc brakes on all four corners stop the truck on a dime. Wheels are 26x16 Forgiato Svolta-T with 37x13.5 RBP Repulsor M/T tires. All work was done by Mark.

Gary's 1972 GMC Jimmy

Long before rooftop tents and adventure trailers, one of the only ways to get off the grid to camp was a short-wheelbase fullsize truck equipped with a camper top. Gary Knight of Harford, Ohio, owns this fine all-original 1972 GMC Jimmy and Blazer camper top combo.

Joel and Jake's 1995 Jeep Wrangler YJ

Joel and Jake Barnewolt's 1995 Jeep Wrangler YJ not only stood out as one of the few Jeep Wrangler YJs prowling the fairgrounds, but also due to the beefy axles peeking out from below the Jeep. This father-and-son duo from Tremont, Illinois, brought their Rio Grande edition Jeep Wrangler YJ sporting the bright mango paint code with axles swapped in out of a M1028 military truck. The front Dana 60 has an Eaton Trutrac limited-slip differential and the rear GM 14-bolt is equipped with a Detroit Locker. We thought the classic Warn 8274 winch looks right at home on the front of the Jeep. Power comes from a Chevy 350ci four-bolt main hopped up with a Comp Cams Extreme 4x4 camshaft, which is mated to a TH350 automatic transmission and NP 205 transfer case. This powertrain combined with 4.88 gears has no issue turning the 37x12.50R17 tires and steel beadlock wheels.

2006 Chevy Trailblazer Cummins

It's hard to miss the exhaust stack protruding from the passenger side of the hood on this 2006 Chevy Trailblazer. After seeing the rig cruising the 2020 Fall 4-Wheel Jamboree Nationals we finally tracked the rig down and found it parked but couldn't find the owner for more information. We took a quick glance up close and could see a Cummins 12-valve engine, Dana 60 front axle, Dana 70 rear axle, and Fox remote-reservoir shocks.

Tim and Amy's 1951 Willys

This 1951 Willy's Overland pickup belonging to Timothy Cottrell and Amy Kinsey of Hillsdale, Indiana, was a barn find and remains mostly original with exception to somebody transplanting a 289ci small-block Ford between the framerails at some point in time.

Dylan's 1956 Dodge

Dylan Johnson's "Virgil" is a 1956 Dodge truck body sitting on top of a 1995 Dodge Ram 2500 chassis. The factory 1995 Cummins turbodiesel engine powers the truck and requires rowing through gears on a NV4500 five-speed manual transmission to get it moving. Dylan says that this unique creation was made through countless hours of turning wrenches with his dad, Brian Lee.
