New engine for the family truckster!

[njsteve]

What did it need? I've been tinkering with this one for over two decades now. Other than the headgasket glitch (a known problem) and relocating the PMD (injection pump brain) to behind the front bumper instead of on the 200+ degree engine, it has been a great truck.

I decided against rebuilding the existing engine because it already has the inherent stress cracks in the original heads between the valve seats (which GM declared to be not an issue in their TSBs), so I would have had to spend a couple thousand for some non-Chinese cast heads... and then new pistons for a thousand more...yada yada - til the cost approached a brand new engine that has all the old weaknesses designed out. That's not even considering that possibility that the block could have main web cracks. Certain batches of these blocks, mainly in the 1997 to 2000 range were machined too quickly after casting and were too green when assembled. The main webs crack right were the bolts go in and travel to the location where the oil squirters were drilled to spray the bottoms of the pistons.

So, in the event the block has no cracks, I already have several 6.5 guys wanting it.
