Hi Guys,
While looking at the GM engine data on the web,
They show Torque figures at 4000 RPM for *both* the 5.3 & 4.2,
and the HP figure at 5200. I find it hard to believe that
both engines hit their respectine peaks at those exact
points and can't seem to find a dyno graph showing the curves.
Anyone know where to find a dyno chart for a fairly stock 4.8?
Thanks,
Mike V
