Unfortunately there’s a pattern of certain individuals who become extremely defensive when reality doesn’t align with their perception or understanding. These people can be easily identified because their immediate defense mechanism is to bring up newer models that make them feel insecure.
Back to your truck, even if you’re just going to run truck on the street, the oil pump upgrade is well worth the cost compared with a new engine. To be clear, there is nothing wrong with the OE pump or it’s design. The issue is caused by shock loading on the crankshaft as a result of the load the supercharger drive exerts on the crank.
Another issue to be aware of is valve spring failure; it’s are not common in general, but the consequences are typically catastrophic. They tend to fail at higher mileage (100k+), and the added heat transfer from the combustion chamber to the cylinder head due to the increased combustion temperatures certainly won’t help. The coolant jacket was never intended to dissipate the heat of developing 200HP more than stock.
In regards to the rotating assembly, it’s robust in factory form, but was never designed for the massive cylinder pressures that F/I can generate, especially at low RPM. At that point the weak point becomes the connecting rods.
Piston and combustion chamber design is also unique for F/I applications. There is a huge difference in air flow characteristics, scavenging, and atomization between an N/A and F/I engine.
If your truck is just a weekend toy, it will probably be fine with just the oil pump
upgrade. But if you’re running it hard, it will eventually fail. And certainly don’t tow with it, that’s asking for disaster.
