My son has a 4.3 S10. It is PITIFUL. Granted, his is a TBI one; but still. It's PATHETIC. It's not detectably better than a 2.8 as far as I can tell, and not any better really than my step bro that has a 3.1 S10. Still totally inadequate. It's bad enough in the minitruck, but can't begin to imagine what possessed some "engineer" to think it was a good idea to put that steaming bucket of horse plop in a full-size truck. AFAIAC they should spend their eternity in Hell driving one around while everybody else gets LQ9s and L92s and such. Definitely not a topic for "performancetrucks.net". Maybe "gasmileagetrucks.net" or something.
96-00 s-series trucks were also easily swapped to the vortec 5.7 with a couple of added wires for 2 additional fuel injectors, a reflashed ECM, electric radiator fans, and potentially recessing the radiator into the core support.
I would imagine the continued evolution of the 4.3 to the LS style ignition and fuel injection opens up some further potential for tuning and power adders that the previous generations couldn't support.
