I’ve been wanting to build a new big block for my square body Chevrolet Dually for the last couple years, and now that it has hurt itself I really need to get on it. Of course, like all car guys I’m spending more time trying to decide what to do than actually doing it. I keep questioning whether or not I should build something new, upgrade what I’ve got, or to go buy a junkyard 8.1. And then here comes Richard Holdener with a big block towing power video. Thankfully, this one here has helped me make my decision and at the same time made me excited for Part 2 to see if one of the other options will be phase two for me too.

So watch and let us know what you think. Which engine would you choose for your tow rig?
