Picked up an 89 Ram 50 with the 2.6 as a winter car for my son. Engine only 106,000 miles, but has a new head. Engine runs well, but runs out of steam at high RPMs (over 4500 RPM). This is problem when the truck down-shifts it falls out of its power band. I am thinking that when the reinstalled the head they didn't centerline the cam properly. Can't climb hills or pass on the highway.

Think I figured out the problem. There appears to be a valve problem with the new head on the engine. Disconnecting #1 spark plug wire does almost nothing to the idle and the engine sounds better. I am getting sparks so it is probably valve train related.
