But as indicated they sure would pull. I moved a completely loaded railroad freight car once with mine. It didn't even whimper.
Oh yeah, pulling power is what these engines do best. Would love to compete in a 'slower' tractor pulling class with a 478 V6... Maybe someday. or a V12...

Here's a tractor with a GMC V12: https://www.youtube.com/watch?v=qr3QdLDJfsU
