Unless Paul is the only one does anyone have the specs for the 6.2 a graph would be grate

if you want hp and torque #s, is it for C or J code?

C code is 135hp and 240 ft pds
J code is 150hp(?) and 270 ft pds(?)

what this C and J stuff :confused:

The C code 6.2L was used in all 1/2 tons and most 3/4 tons. It's the most common 6.2L.The J code engine was used in 1 tons and some 3/4 tons. You can tell a C from a J by looking at the intake manifold. If it has an EGR valve, it's a C, if there's no EGR, it's a J. But, replacing the C code intake with a J gives you a little more hp and torque so it can be difficult to indenify them just by the intake. I'm sure there are other ways to tell them appart.

at what rpm are the foot punds

1800RPM

the hp is at 3600 rpm...just in case someone wanted to know;)

Great info. thanks....I got a Banks "sidewinder" turbo to put on my 6.2 I can't wait to get it put on......:D :D
