Why it is only available on lower class trucks
It is a fantastic 'car' engine though and another why it is available on the
lesser class trucks...AKA 1500's...AKA half ton
Same or similar to why 'P' class tires are NOT offered on +8K GVWR trucks. They
are designed for 'cars' or 'passenger cars'
Think this is the correct one for the OP's half ton SUV
GMLS866.2L L86 6.2L
I wouldn't post a hp/tq curve for a 6.2L and say that's the reason it's not in a HD truck because I can post the exact same hp/tq curve for a 6.0L making peak HP and tq at those RPM's.
I agree, however how many engine hours can an aluminum block motor sustain running at max torque RPM and not have heat stress take its toll compared to an iron block?
