Not that they are bad engines; they are not suitable for hot rodding. If they were I'd bet they'd be a lot more popular now.

I had a 478 in my '62 GMC 6500. It would go 62 MPH. But as mentioned above "they are heavy, low revving truck motors, not suitable for any performance of racing use".
Slow revving with a whole lot of torque. Hot Rodding one would be like Hot Rodding a 673 Mack. They just weren't built for speed and trying to make one go fast would take a whole lot of money, if even possible.
But as indicated they sure would pull. I moved a completely loaded railroad freight car once with mine. It didn't even whimper.
