Default 2004 Vortech 5.3 specs

New specs on the 5.3 are now 295 hp and 330 ft./lbs. at the same rpm as 285 hp and 325 ft./lbs. occured before (5200rpm/4000rpm).

Anyone know what gave the boost to the 04 engines.

GM powertrain had these specs listed already in previous years for the van and a few other applications of the 5.3.

Head architecture and cam, maybe. Perhaps better tuning. Just guessing.
