Trick Flow Specialties is once again building the engine that will be part of the prize package awarded to the Summit Racing SuperSeries Top Class Champion. Last year, Trick Flow built the 565 cubic inch big block Chevy for the American Race Cars dragster that 2012 Top Class champion Tim Butler is campaigning this season.

This year, Trick Flow is going Blue Oval with a 598-cubic-inch big block Ford.

We’ve covered short block assembly in our first post and top-end installation in the second article of this series. That just left carburetion, ignition, and external accessories separating the engine from its date with Trick Flow’s Superflow dyno:

Holley Gen 3 Ultra Dominator carburetor
MSD Flying Magnet crank trigger kit and Pro-Billet distributor
Meziere electric water pump
Moroso vacuum pump, external oil pump, and drive kit
ATI Super harmonic damper and timing pointer

The Trick Flow guys fabricated a front motor plate from quarter- inch thick aluminum to hang the front-mounted accessories (water pump, vacuum pump, and oil pump). They also put together hose assemblies for the oil pump and vacuum pump using Summit Racing -12 AN fittings and Earl’s Pro-Lite 350 hose.

With the last bolt torqued, it was time to see what this collection was worth in the horsepower department. Trick Flow hooked the 598 to the dyno’s life support systems, filled the sump with Joe Gibbs Driven 15W50 oil, and made some break-in pulls to get the engine settled in and ready to make some power.

And boy, did it ever. After some minor fiddling with the timing and jetting (29 degrees total timing, #102 jets front and rear) and adding a second one-inch-tall carburetor spacer to get some extra intake plenum volume, they let the 598 rip.

After three pulls, the engine made its peak numbers—1,025 horsepower and 836 pounds-foot of torque—and hit those points on virtually every subsequent pull.

“This is a very strong, very consistent engine,” said Trick Flow’s Todd Hodges. “It’s even more impressive considering we built it with off-the-shelf parts. Anybody that’s put engines together can duplicate this one and get very similar numbers.”

That new owner, the 2013 Summit Racing SuperSeries Top Class champion, will be getting all that big block Ford power in a shiny new dragster built by Maddox Race Cars (along with a ton of other loot). Our word of advice for the champion-to-be? With great (horse)power comes great responsibility—for winning races, that is.
