Yeah my uncle just bought a new to him 1965 Ford F700 grain truck full load is supposed to be 24,000 GVW. It has a “high output” 292 Y block 170hp/279TQ.
Another week or two and I’ll be playing truck driver hauling grain for him, it’ll probably pull at least as good as the 1953 Chevy C60 with the 235 BlueFlame 6 that I used to haul in.
