The Australian category will be abandoning their current bespoke five-liter V8s as part of their new rules in favor of cheaper, longer-lasting box engines from Ford and Chevrolet.
While Ford was quick to nominate the engine for its Gen3 Mustang, a 5.4-liter version of the 5.2-liter aluminator, it took GM longer to land on its preferred engine architecture for the Camaro.
It has now been confirmed that the displacement of the Chevrolet unit will be 5.7 liters, but further details have yet to be determined by the GM engine homologator KRE.
This includes which series the engine will be based on, explains the Supercars motorsport director, that it may not be so easy to name it as an LS or LT engine.
“[KRE] are well advanced, but it is no longer an off-the-shelf road car engine, “said Adrian Burgess.
“Our engines have never been. Like all of these things, they are a collection of parts.
“Now they are working closely with GM on what they think is the best package that meets the financial criteria we have set – we are setting a target number that they can hopefully achieve [for] Reliability and remodeling costs.
“So it’s complicated to get all of these metrics we’re trying to stick to. It’s not that easy to say that it is an LS3 block or LS3 heads or bespoke heads or an LTR block Although outside people might think it is that simple, it is not.
“There are many factors in this thing and supercars are not in a position to tell you what it is until these guys are happy with what they are presenting and they are still working on it.”
Supercars previously said it was confident it could parry the two engines despite the differences in capacity and the fact that the Ford is an overhead cam and the Chevrolet is a push rod.
Ilmor Engineering in the US is on standby to help with this parity process in case supercars need it later in the development process.
