A mod­est ap­proach to an 11-sec­ond 7.3L

At first glance, the av­er­age per­son would have no clue to the level of row­di­ness that's con­cealed in Tony Salokas' '01 F-350. With the fac­tory 16-inch Al­coas, ' 05 front clip, and King Ranch badg­ing, it would be easy to as­sume cos­metic changes are the ex­tent of its up­grades. But stum­bling across this truck at a stop­light would leave you scratch­ing your head. It's one of the nas­ti­est Heui-fired 7.3L Power Strokes you'll find. Need proof? How about a 7,300-pound Su­per Duty that runs mid 11s on fuel?

Un­be­knownst to most liv­ing out­side the 7.3L belt­way, huge break­throughs in tech­nol­ogy and per­for­mance have been made over the last 5-7 years—and Salokas’ truck is a per­fect ex­am­ple of all of the progress that’s been made. Prop­erly matched air­flow via the heads, cam, and turbo all work­ing well to­gether, cou­pled with hy­brid in­jec­tors and op­ti­mal tun­ing, cul­mi­nates in a 7.3L churn­ing out nearly 800 rwhp.

THE BEAST WITHIN

Built by Car­son Stauf­fer Diesel, the 7.3L en­gine in­cor­po­rates a Dyno Proven gir­dle and ARP main studs, Man­ley con­nect­ing rods, fly-cut cast-alu­minum Mahle pis­tons with de-lipped fuel bowls, and a Stage 2 cam from Gear­head Au­to­mo­tive Per­for­mance. The block’s water jack­ets were also par­tially filled with Hard­blok, along with the block (and heads) be­ing cut to ac­cept fire rings. A set of Car­son Stauf­fer Diesel’s Stage 2 fire-ringed heads fea­ture ex­ten­sive port­ing and up­graded valve springs and fas­ten to the block via H11 head studs.

Go­ing big on the in­jec­tor side yet keep­ing things streetable is a set of 300cc/200-per­cent noz­zle com­pe­ti­tion hy­brids from Swamp’s Diesel Per­for­mance. Keep­ing up with the oil de­mand of the hy­brids is the com­mend­able Gen3 high-pres­sure oil pump from Swamp’s. With a Beans Diesel Per­for­mance sump in the tank, a fuel sys­tem from Marty’s Diesel Per­for­mance em­ploy­ing an Aero­mo­tive A1000, and a reg­u­lated re­turn kit from Car­son Stauf­fer Diesel, a steady stream of diesel makes it into and out of the in­jec­tors. Swamp’s cus­tom PCM tun­ing pro­vides max­i­mum power and good driv­abil­ity.

When it came time to pick out the per­fect tur­bocharger, Salokas spec’d one from Barder Turbo Ser­vice. The Borg­warner S400-based unit fea­tures a 75mm, 6-blade, bil­let com­pres­sor wheel, and an 87mm tur­bine wheel re­sid­ing in a 1.10 A/R ex­haust hous­ing. A T4 turbo kit from Car­son Stauf­fer Diesel mounts the S475 near the fac­tory lo­ca­tion and 3-inch-di­am­e­ter pip­ing routes air into an Al­radco in­ter­cooler, then to the en­gine.

BTS TRANS­MIS­SION

Bul­let­proof­ing the 4R100 au­to­matic was left in the hands of Brian’s Truck Shop. While un­der the BTS roof, the trans­mis­sion would be graced with 300M in­put, in­ter­me­di­ate, and out­put shafts, as well as a cus­tom-tai­lored valve body and other se­lect in­ter­nals. A 2,400 rpm stall, triple-disc torque con­verter built by Pre­ci­sion In­dus­tries was also in­cluded to make the S475 as driv­able as pos­si­ble on the street.

IT’S FUN TO SEE WHAT KIND OF POWER YOU CAN GET OUT OF THE 7.3L, AND IT’S CHEAP TO GET STARTED (COU­PLE HUN­DRED BUCKS FOR A MO­TOR). YOU CAN’T DO THAT WITH A DU­RA­MAX OR CUM­MINS. —Tony Salokas

This is what you get when you bend a cryo’d forged rod at the 600-rwhp mark: big­ger and bet­ter. A balanced and blueprinted short block from Car­son Stauf­fer would en­tail a Dyno Proven gir­dle, par­tially filled block, Man­ley forged I-beam con­nect­ing rods,...

A reg­u­lated fuel re­turn sys­tem from Car­son Stauf­fer Diesel makes use of a pol­ished, ad­justable Aero­mo­tive reg­u­la­tor. Salokas fab­ri­cated his own mount for the reg­u­la­tor, and he keeps fuel pres­sure set at 68 psi.

Se­ri­ous in­jec­tors call for a se­ri­ous fuel sys­tem, so Tony went with the 1375 Kit from Marty’s Diesel Per­for­mance, which in­cludes an Aero­mo­tive A1000. A Beans Diesel Per­for­mance fuel tank sump con­nected to 5/8-inch fuel line gets things started, and...

Keep­ing plenty of oil vol­ume avail­able for a set of Swamp’s Diesel Per­for­mance 300/200 hy­brid in­jec­tors is a Gen3 high-pres­sure oil pump, also from Swamp’s. It works in con­junc­tion with the stock 17-de­gree pump mounted in the fac­tory lo­ca­tion....

If the op­por­tu­nity presents it­self, Tony is al­ways game for a lit­tle dirt drag ac­tion. Take it from us, this truck can build up a lot of steam in just 300 feet worth of track.

Keep­ing the rear leaf springs from twist­ing and the Ster­ling 10.5 from ro­tat­ing, Salokas fab­ri­cated his own trac­tion bars. They uti­lize bolt-on axle mounts in­tended for Cal­tracs trac­tion bars, while the frame mounts are welded in place.
