stock torque curves

[DLeno]

wondering if anyone has torque / HP curves for the stock SO Cali SO, and HO trucks from 2003-present.

are you looking for dyno sheets?

The Cali truck will be less than the National Standard Output it only has 235HP but I bet the curve looks pretty much the same.

great info. thanks guys. No, I'm not looking for dyno runs -- I'm looking for marketing graphs like big daddy T posted. I just wanted to have all the stock claims in one place. need the 235 Cali SO and the 325 600 now.

Good luck on the 600. If you can find it. Can you post it.

I don't think I've ever seen a torque/hp curve for the 600 either, but I if you look at the curves for the 305/555 shown in Big Daddy's link above, and extrapolate the curve to 600 fl-lbs, that it would be pretty close. Note that the 555 reaches peak torque at 1400 RPM while the 600 reaches peak torque at 1600 RPM. Extrapolating the 555 curve seems to fit this theory.



My guess is that the ECM in the 600 has raised the waste-gate limit to 600 ft-lbs. The rest of the 600 mods were to keep the EGT's down and longevity up with the increased power.

Here is a Stock and Modified dyno chart for a 2004. 5 600 6-speed with one of our prototype modules on it.
