It’s a tough motor and reliable as an anvil. It is head and shoulders better than a 350 small block. Great motors.
Yep. Had one for 10 years in a 2004 Chevy 2500HD. Absolutely dead reliable. On the 4-speed transmissions low end torque was a little lacking, but if you let that engine rev between 3,200RPM and 4,400RPM it would pull extremely well.
I only had 2 issues and they common to that engine:
1) Exhaust manifold bolts will break on the front and back cylinder of each side. This is a very easy fix for any exhaust shop that knows what they are doing.
2) Check engine light for knock sensor. The Knock sensors are located in a hole the valley of the engine. The rear sensor tended to collect moisture, corrode, and fail. There was a TSB for removing a piece of foam and making a dam around the sensor cover with RTV silicone.
Both of these were easy fixes and not very expensive. If I had another small block V8 I'd own a GM 6.0L engine in a heartbeat.
