Like most other engines, the Cadillac Northstar 4.6 V8 has evolved over the years. In 1994, the first Northstar V8 (L37) was joined by a second version (LD8) with a different cam profile that lowered peak horsepower slightly to 270 hp but increased torque output in the lower rpm range for improved throttle response and quick acceleration.  In 1994, a downsized and somewhat less powerful version of the original Northstar V8 was introduced in the Oldsmobile Aurora. The L47 4.0L V8 was essentially the same engine as the larger 4.6L V8 but with a smaller bore size (87mm vs. 93mm). The L47 4.0L V8 was rated at 250 horsepower.  In 1995, the power rating of the L37 4.6L V8 (VIN 9) was bumped up slightly to 300 hp, and the LD8 4.6L V8 (VIN Y) was upped to 275 hp.

The two basic versions of the 4.6L V8 (275 and 300 hp) are still being used in model year 2003, and there are no plans to replace this engine in the immediate future. So it looks like the Northstar V8 will continue to enjoy a long production run.
