Cadillac Northstar is 4.6L V8. Olds Aurora used a variant built as the 4.0L and produced 250HP. The detuning was in the cylinder heads to match the smaller engine displacement. The Aurora V8 was featured in IRL racing and was pitted against the Infiniti V8....Olds was victorious in about 99.9% of the races.
