I have a 1997 extended cab 2500 with the 454 engine and need to know the stock horsepower. It is not listed in the manual.

Thanks.

Here's what my Chilton's manual lists for the 454:

290HP@4000RPM 410TQ@3200RPM -- standard engine

290HP@3400RPM 385TQ@1800RPM -- HD engine

  Ha!! So GM Customer service, ive already been talking with someone on your email team and there is nothing they can do. So pretty consistent with everyone else’s experience- you can do NOTHING.. worthless emails. Sure glad i have 4 GM cars on our family cuz now its clear you dont care.. Sad and pathetic.
