Up next Old School Power!

Hastings Foote’s 1997 Ford F-250 Power Stroke Coming across a clean old body style Ford isn’t as easy as it used to be. Twenty-plus years of changing seasons, exposure to salt, and general wear and tear definitely takes its toll on these square bodied beauties. While the 7.3L Power Stroke under the hood might last forever, the rest of the truck usually doesn’t keep pace. Still, the affinity for these aging Blue Ovals runs deep. If you’re into them, you’re really into them. And if you add in a few modern performance upgrades like Hastings Foote did with his ’97 F-250, you’ve got a classic diesel with more than just cosmetic appeal. Despite making an estimated 450 hp at the rear wheels, the 141,000-mile 7.3L Power Stroke powering Hastings’ OBS remains 100 percent stock (not even the valve springs or pushrods have been replaced). Installing a set of Rosewood Diesel Shop’s 160cc, 80-percent over nozzle, Stage 2 injectors is the furthest he’s ever gone into the engine. A T500 high-pressure oil pump from Terminator Engineering has no problem maintaining plenty of oil volume for the Stage 2 sticks to use. Untouched Long Block After obtaining the truck five years ago with just 131,000 miles on the odometer, Hastings is yet to break the seal on the low-mile 7.3L. To date, a set of Stage 2 injectors from Rosewood Diesel Shop represent the furthest he’s dug into the 444 ci V-8. Keeping the oil side of the injectors happy, and replacing the volume-limited 15-degree factory high-pressure oil pump, is a T500 unit from Terminator Engineering. Ridding the engine of its weak, cam-driven factory lift pump, an electric OBS competition fuel system and regulated return from Irate Diesel Performance handle fuel supply duties. All PCM calibrating is handled by Power Hungry Performance, and Hastings navigates his PHP tunes on the fly via a Hydra Chip. Doing away with the factory dual tank and restrictive fuel selector valve setup, Hastings installed a 38-gallon fuel tank intended for a Bronco (Spectra F26B) in the rear. From there, a bulkhead fitting allows diesel to gravity feed toward an Irate Diesel Performance OBS competition fuel system, complete with a Fuelab 4140 lift pump. Hastings opted to run one of Irate Diesel Performance’s regulated return fuel systems to increase fuel supply being sent to the injectors (and also to rid the lifter valley of the factory fuel bowl). He keeps the adjustable Fuelab pressure regulator set at approximately 65 psi. Deep Breaths Opening up airflow for the 7.3L, a T4 turbo mounting system from Irate Diesel Performance is employed, which essentially allows any T4 flanged charger to be bolted into place. Hastings’ turbo of choice is an S366 from BorgWarner, which sends close to 40 psi of boost through an aluminum intercooler from a 7.3L Super Duty application. Aluminum intake plenums with 3-inch diameter inlets, 3-inch intercooler piping and intake Y, and stainless steel up-pipes from Irate Diesel Performance complete the free-flowing air path into (and out of) the engine.Subscribe Our Weekly Newsletter Having the transmission built locally, the E4OD automatic was reinforced by Ray’s Automotive in Culpeper, Virginia. The four-speed slushbox benefits from a PATC triple disc torque converter, upgraded clutches, a John Wood Automotive valve body, and a cast-aluminum, extra capacity pan from PML. A lock up box provides Hastings with total control over torque converter lock up while drag racing or sled pulling the truck. Running high 8’s in the eighth-mile was impressive to see from Hastings’ old-school Ford. Granted, a truck that runs a 14-flat in the quarter isn’t blazing by today’s standards, but it’s more than enough to keep up with the majority of the Big Three’s latest and greatest. To improve the truck’s ride comfort, Hastings installed a PMF reverse shackle kit. This is a modification he believes makes the OBS Fords ride as good as (or better) than the newest Super Duty’s on the market. PMF traction bars keep the rear 10.25 Sterling from wrapping under load. They’re built from 0.250-inch wall DOM tubing, bolt to the frame via brackets, and utilize block mounts to attach to the axle. Fortified E4OD In order to harness the 800 lb-ft of torque the 7.3L would send to the wheels, Hastings turned to his hometown transmission shop, Ray’s Automotive, to beef up the E4OD. The four-speed would receive upgraded clutches, a John Wood Automotive valve body, PML deep pan, and was topped off with a PATC triple disc torque converter. To keep the E4OD cool, Hastings installed an Xtruded double stacked transmission cooler from BD Diesel. For competition purposes, a manual lock up controller built by 7.3L guru Matt Maier is utilized. Like the rest of the truck, the interior screams low miles. An Edge CTS2 monitor helps keep an eye on the truck’s vitals, as well as read and clear DTC’s if the need arises. The task of tying all of the truck’s modifications together was left in the hands of Power Hungry Performance—the company that practically invented custom tuning for the 7.3L. Hastings navigates tunes on the fly thanks to this Hydra Chip, which is made by Power Hungry. Solid Axle Conversion With just one pass under his belt at the drag strip—and the original Dana 50 TTB incurring plenty of damage—it wasn’t hard for Hastings to decide to replace it with a solid axle. Sourcing a Kingpin Dana 60 from an ’89 F-350, he would perform the swap himself and never look back. Hastings later improved the truck’s front end ride quality by installing a reverse shackle kit from Precision Metal Fabrication (PMF). A BD Diesel Xtruded double stacked transmission cooler mounted in the bed ensures the E4OD is never subjected to extreme heat. Hastings told us it has no problem sustaining 140 to 160 degrees, even while hot lapping at the drag strip or dirt drags. Given everything that’s been done to the truck yet finding the factory Alcoas still bolted to the axles says a lot about Hastings. He’s an OBS Ford fan, and no die-hard enthusiast appreciates the forged-aluminum Alcoa wheels quite like they do. Hastings wrapped the 16×7’s in 305/70R16 BFGoodrich All Terrain T/A tread. Big Things To Come While a lot of enthusiasts tend to shy away from pursuing horsepower with a 7.3L, Hastings enjoys the challenge. “They are such a natural underdog,” he told us. “They have a lot of shortcomings [with HEUI, the stock turbo, and the E4OD], so you have to know when and where to modify them to make them better.” With a clean-burning, 450hp being made on a relatively tight budget, we’d say he’s done a good job living up to that line. But with plans to add bigger injectors and an S400 over the winter, he might just have an entirely different animal on his hands come spring. DW While he’s spent time on the drag strip and hooked to the sled, Hastings is a big fan of dirt drags. He told us that, thanks to the light race weight of his OBS (just 6,900 pounds), he can run neck-and-neck with heavier trucks making considerably more horsepower.
