372ci Windsor with Gurney Eagle head – Dubai Car News

WWhat Hatford did with its original GT40 Le Mans racers in the late 1960s will forever be etched in history. These GT40s scored four Le Mans wins on Trott (1966-1969), and in the process thoroughly reconfigured a certain Italian racing team that had previously dominated. Racer, constructor and team owner Daniel Gurney played a major role in the engine department of these GT40s after Ford withdrew from the program, leading to the creation of Windsor-based Gurney-Weslake engines by Weslake Engineering in the UK. Designed and developed. .

GW Mill drove the GT40 to its last two Le Mans victories in ’68 and ’69. This era was an important chapter in Ford’s racing heritage that lives on in the Gurney Eagle Heads you see here on Bernie Roshman’s Windsor.

“The heads are impossible to find,” says Bernie. “You could only buy them from Gurney, and as you’d expect, they stopped making them a long time ago.”

Bernie’s ass started out as a 351 Windsor and has been bumped up to 372 cubes using a steel crank, Chevy rods (you read that right!) and high comp pistons. “They didn’t have stroker kits like that, so that’s what they used,” says Bernie of Shave Rods.

The engine was already in good shape when Bernie got it, so he had it freshened up for street duty by Steph Radvanovic of SR Engines. “We changed the cam to a John Marshall solid roller with T&D shaft rockers,” says Bernie. “I also had the trumpets built to fit the new Weber injection, but you’ll notice it doesn’t have the intake manifold – the throttle bodies go straight to the head.”

A complex linkage allows Bernie to open the taps on all eight cylinders simultaneously, and he insists he won’t overwhelm them with massive foam filters. “They have metal filters, but other than that I’ll play them as they are, because I want to hear them!”

MoTeC brains manage the whole shebang with another modern touch in the form of MSD ignition and electric water pump. Oiling is handled by a conventional internal pump and wet sump.

In its current guise, the rare donkey made a healthy 550hp, revving to around 7500rpm and sipping PULP 98. “People said we could get it to 600 if we wanted to. With those heads it really wants to rev,” says Bernie. “But it’s only for a streetcar, so I don’t see the point.”

The street car in question is Bernie’s Pro Street XR Falcon, which is currently being assembled for its unveiling. Street Machine Summernats 35. “I’m sure there will be people who will point out that I’m using such a historic race engine in a road car, but I’ll be doing some racing under the belt,” says Bernie. . “The guys think he should easily run 12 with the power he has now.”

The big question though is whether we’ll get to see those beautiful trumpets sitting out the bonnet or not. “Sadly, no,” says Bernie. “We couldn’t make it work with fuel rails, so it would have a cowl scoop instead.” Regardless, we can’t wait to see this stunning mill in its new Falcon home when it’s unveiled at the ‘Nats.
