Despite the M2B's lack of success Herd said of the team, "Everyone was ten times more determined to do better the following year." On the design of the car he reflected that, "our emphasis tended to be more on the elegance of the chassis structure rather than on the design of a really quick racing car" and that, "we ... tended to go towards technical ingenuity and bullshit rather than racewinning engineering". Team member and later manager of the organisation Teddy Mayer said, "Our main problems were with the choice of the Ford engine." Bruce McLaren's personal secretary and author Eoin Young concurs. The winners of the 1966 Drivers' and Constructors' championships, Jack Brabham and his eponymous team, used a Repco-modified and badged Oldsmobile engine. It produced approximately 290 bhp – less than the Ford – but its light weight and reliability rendered it effective. Despite having used the Oldsmobile in sports racing cars, the McLaren team discounted it. Afterwards, Mayer said, "We considered it, but the kind of modifications which Repco did were well beyond our resources, and I doubt very much if we could have done any more with it than we did with the Indy Ford."
