I’ll add that decades ago I drove an F600 tow truck. It had a 300-inch six cylinder gas engine and it hauled all sorts of heavy stuff, for years and years. Just not quickly.
Next one was a Chevy C60 with a gas 366. Same story.
Every school bus a few decades ago had a gas 366 or a gas Ford 470 (a small-bore, long stroke truck version of the 429/460). The kids got to school.
None of us NEED a diesel pickup with 800 ft/lbs.
We LIKE them. A lot. But the 6.0 gas Chevy will get the job done for sure, even with a heavy trailer behind it. We ran them as work trucks for years, treating them terribly, working them to death. Except they wouldn’t die.
