MAX torque at 800rpm?!?!

I was just told that the 300 I-6 develops MAX torque at 1200 rpm, with 10° timing. I have mine set to 14°, so that would make it roughly 800 rpm, right? No wonder it pulls so hard at idle! I can climb real hills at 35mph in 5th gear!!! If I try to go faster on a steep hill, it just slows to 35! A change of timing might be in order.....
