We spend a lot of time oohing and ahhing at restomod trucks around these parts. If we had a nickel for every Coyote-swapped Bronco we've come across in the last few years; we might have enough coin saved up for a down payment on one. Okay, not quite that many. But if you're more of a GM/Chevy kind of fella, this 1972 GMC Jimmy 4x4 swapped with a firebreathing LS7 V8 will cure what ails you. At least to some subjective tastes, the GMC looks much better than a Bronco from the same period.
As the last model year in the first generation Jimmy based on the GM K10 line of pickups and SUVs, the 1972 model is a downside more valuable than its forbearers as a result. Rising sales during this period from GM lit a fire underneath the rear-ends of Dodge and Jeep during this period, who released the Ramcharger and Cherokee, respectively, to counter the Jimmy and its Chevy K5 Blazer cousin. Under the hood in those days, Blazers and Jimmys left the factory with four different straight-six and V8 options ranging from 250 cubic inches (4.1 L) up to 350 cubic inches (5.7 L). The latter of which was a particularly potent engine in the lineup at the time.

But compared to those ancient engines from before SMOG regulations, the 7.0 liter GM LS7 engine out of a C6 Chevy Corvette Z06 might as well be from another planet. This particular Jimmy was acquired bone stock by its current owner back in 2021. Before long, the old motor and the rest of the drivetrain were unceremoniously freed from their confines under the hood of this truck. From there, the new LS motor was installed using a set of custom motor mounts. But not before the entire body was painstakingly lifted off the frame so as to restore and rust-treat the whole package.

Once that was done, a GM 4L80E four-speed automatic transmission was mated to the LS7 motor. Further goodies like an NP205 dual-range transfer case, a Dana 44 off-road-optimized front axle, and a 12-bolt rear axle made for a package that's even more capable than whatever GMC offers stock from the factory these days. No, seriously, it begs belief how GMC can't build a decent off-roader anymore without it straight up just being a pickup truck. In any case, this Jimmy's 2.5-inch lift kit and hearty Bilstein shocks with locking front hubs will make light work of most off-road trails.

Its wicked bright green paint with a white vinyl roof on 15-inch polished steel wheels is sure to turn heads while it does so. Check out the Bring a Trailer auction page right here if you want to learn more.
