A 2002 Chevy duramax has 300 horsepower stock
145.
The 8.1L vortec comes stock with 330 hp and about 450 pound feet of torque.
Probably about 240 or close. Move to a 96 and it's a lot more. The Vortec started in 96 with the 350 (5.7) and 454 (7.4). I understand the Vortec 5.7 had a little more power than the non-Vortec 7.4, and the Vortec 5.7 has 250 horsepower.
Chevy never made a 327 vortec. the last time they produced a 327 was in 1969, while the first vortec was made in the early 1990s.
