2009 Ford F-350 Super Duty - The Outsider

A Ford Infiltrates The Top Ranks of the Pulling World

For years, we've known the Ford 6.4L Power Stroke has serious horsepower potential. Still, most 6.4L owners have been reluctant to try their hand in the sled pulling game -- an arena where Cummins and Duramax mills rule the roost. However, with the purchase of an 2009 Ford F-350 Super Duty, Morgan Primm set out to prove that a Blue Oval can compete in the top ranks of the pulling world.
After ditching the truck's service bed, a prompt teardown of the 200,000-mile common-rail V-8 ensued, followed by a competition rebuild using a fresh block. Forged connecting rods from R&R Racing Products, fly-cut MaxxForce 7 pistons, and a billet Stage 2 camshaft from Colt Cams now reside in the short-block with the factory crank. The heads were fully ported, matched to a custom-ported intake manifold, and fitted with Midwest Diesel and Auto 120-pound valvesprings. The worked-over factory heads attach to the block via ARP studs.

Turning to the fuel system, Morgan came up with a one-off dual fueler configuration that effectively moved the valley-mounted K16 high-pressure pump out front and combined it with a second one. Ported rails allow increased fuel volume to make it to the injectors, which utilize six-hole, 100-percent-over nozzles from Midwest Diesel and Auto. Finally, there is no lack of low-pressure fuel being supplied to the K16s thanks to an Aeromotive A1000 lift pump.
Because Morgan planned to run in the Midwest region's ultra-competitive 2.6 Class, sourcing the correct turbo was key. So River City Turbo built him a 2.6-legal charger sporting a billet compressor wheel from Columbus Diesel Supply. Cooling off intake air is a PT3000 air-to-water intercooler from Precision Turbo and Engine.
The initial fine tuning of the engine was a chore because the truck's cab-and-chassis PCM doesn't share the same tuning support as standard Ford F-250 and F-350 trucks. However, once the electronic gremlins were solved, courtesy of H&S Performance's MCC software, Morgan had an engine that would fuel all the way to 5,800 rpm -- where he set the rev limiter. A typical pull consists of the truck leaving the line at 5,500 rpm and carrying at least 4,500 down the track. "The engine likes to turn rpm, so that's where we run it," he told us.
Photo 3/13   |   Morgan’s 6.4L Power Stroke features a balanced rotating assembly consisting of the stock crankshaft, R&R Racing Products forged connecting rods, and machined and thermal-coated MaxxForce 7 pistons with 0.125-inch-deep valve reliefs. The 15.5:1 compression engine also benefits from a Stage 2 Colt Cams billet camshaft, ported heads, Midwest Diesel and Auto 120-pound valvesprings and chromoly pushrods, and ARP 2000 head studs. An electric water pump is also employed (along with a custom front cover) in order to survive the 5,500 rpm the engine regularly sees.
So far, Morgan's Ford has been competitive when pitted against some of the toughest running 2.6 trucks in the country. Top 10, top five, and even a few wins are under the Super Duty's belt already, and the truck shows improvement nearly every time it hooks.
As if taking on the likes of the 2.6 Class heap wasn't enough of a challenge, the truck's wheelbase was recently shortened to 158 inches so Morgan could also compete in the local 3.0 Class. You read that right, with a simple turbo change, the truck will be taking on even stiffer competition! But, if you ask the truck's owner, he'll tell you he has nothing to lose by campaigning a Power Stroke in a Cummins- and Duramax-dominated world. "Being that it's a Ford, no one ever pays any attention to it—until it goes down the track…"
