Default 03 2500HD ????????? Hp & Torque Numbers

Gm rates these motors at 300 horsepower at 4400rpm and 360lb-ft of torque at 4000rpm That just seems like a very tight power ban. Do you think the moter actually makes more power at a higher RPM? My 03 feels like it pulls hard to 5200-5300. Does anyone have stock RWHP #'s for an HD with a 6.0? Thanks.

mine might be WAY off because they are the highest stock 6.0 numbers I have EVER seen...and they are only peak numbers (I have no graph because I got them with the results of a smog test in Ridgecrest, CA....it was not an actual dyno run but it was on a Dynojet dyno)

291 RWHP
321 RWTQ

the numbers do jive with the best time of 15.32 I have run.....but I still don't really believe them

BTW...mine is a regular 2500...not an HD
