THE Ford engine which will power next year’s Gen3 Mustang Supercars will undergo further durability testing in the United States.

Both the 5.4-litre Ford Coyote and 5.7-litre Chevrolet pushrod counterpart recently completed a bout of testing Stateside.

Herrod Performance Engines figurehead Rob Herrod revealed a minor valvetrain issue had popped up during the process at Ford’s Dearborn headquarters.

While fully confident of his product, which clocked more than 5000km on a state-of-the-art dyno in its recent American voyage, Herrod and Ford will go above and beyond with extra running in December for a freshly built engine.

“Everything to date has run really well but we had a little bit of a valvetrain issue where we’ve had to go back and revise the valvetrain, which has held us up time-wise,” Herrod told V8 Sleuth.

“So what we have decided to do now is we’re going to do a whole new fresh engine.”

It should be noted that the fresh engine will be almost identical to its predecessor, just with the valvetrain revised.

“That’s going to go back over for December and we’re going to run a full month of durability in December,” Herrod continued.

“We know we’re not going to have any real problems. We’ve got no real issues.

“We’ve come up with some potting issues, like electrical connectors, which instead of having internal they’re going to be glued in.

“We have worked out where our flaws were. There’s no real problems with the engine.

“We just want to go there in December and it’s going to run for the whole month, we should do 10,000km, non-stop.”

Herrod will travel to Dearborn, Michigan following the Adelaide 500, which will conclude the 2022 Repco Supercars Championship on the first weekend of December.

Ford will be represented by five teams and 11 cars next year, namely for Dick Johnson Racing, Tickford Racing, Walkinshaw Andretti United, Grove Racing and the Blanchard Racing Team.
