In our last installment of the Cadillac Northstar story, we reviewed the engineering decisions made early in the engine’s development. From the sensible choice of 4.5 liters of displacement (4.6 in production) to the hubris of consumer focus groups filled with aging current owners, the project rolled forward but faced many engineering challenges. The development was daunting as Cadillac’s first dual overhead cam V8 engine after decades of overhead valve power plants. The difficulty of pairing a cast aluminum block to iron cylinder liners was complete, but engineers opened up a new can of worms with the induction system.
