Bill:
Do you have a link to a similar torque curve chart for the Jeep 3.7L V-6
and/or the 3.8L V-6 used in the '07 Wrangler?

Re: Torque/HP curves
Hi Dave,
That would be a very high performance engine with over 330 degrees
of cam duration and wouldn't idle worth a sh*t below 1800 RPMs, like
this Chevy small block: http://stunmun0.tripod.com/index/hp.jpg Most of
us are less than three grand, like this Kraut V6:
