Back in the day, an S475, 400/400 in­jec­tors, and good tun­ing would barely knock on the door of 700 rwhp—but now things are dif­fer­ent. 7.3L die-hards like Salokas are mak­ing well north of that on 300/200s thanks to bet­ter head flow, turbo tech­nol­ogy, and tun­ing. So far, this Su­per Duty has cleared 714 rwhp on the dyno, but ac­cord­ing to the track is send­ing 780 ponies to the pave­ment. Cur­rent goals for the truck are to run an 11.5-sec­ond quar­ter mile on fuel and put to­gether an 11.0-sec­ond pass on nitrous. We don’t see that be­ing a prob­lem. It’s what comes af­ter that that has our in­ter­est piqued. You could very well be look­ing at the next 7.3L to run 10s. So much for be­ing called di­nosaurs. UDBG

This is some­thing you don’t al­ways see in the bed of an 11-sec­ond diesel: a goose­neck ball. Salokas told us the truck drives so well that he wouldn’t be afraid to tow with it if he had to.

While the fac­tory 3.73 gears still re­side in the front and rear dif­fer­en­tials, the rear 10.5 was fit­ted with a Detroit True­trac. Other than the BTS trans­mis­sion, Salokas says this is his fa­vorite af­ter­mar­ket com­po­nent he’s added to the truck. “You can...

With a set of Swamp’s Diesel Per­for­mance 300/200 in­jec­tors and a Gen3 high-pres­sure oil pump feed­ing the en­gine, hav­ing the guys at Swamp’s dial in the truck’s tun­ing was a no-brainer. Salokas nav­i­gates be­tween cus­tom tunes via a Hy­dra Chip from Power...

To harness ev­ery­thing the built 7.3L could throw at it, Salokas let the ex­perts at Brian’s Truck Shop bul­let­proof the 4R100 au­to­matic. Forged 300M in­put, in­ter­me­di­ate, and out­put shafts sit in­side the slush­box, as well as a cus­tom-tuned valve body and...
