  1. I had a '72 Biesemyer. Bought it for $2500. 460 big block with a .30 over cam.. Berkeley jet, seated 8, would barely get to 50mph. It did throw a nice roost though.

  2. Really cool to see a new episode of Road… err "Boat Kill" make a comeback!
    As for what happened, my first educated guess would be running too lean and too much boost with the stock compression ratio.

  3. I miss these Roadkill episodes. I also miss the 1970s. My uncle had one of those jet boats back in the day with the coolest gas pedal. It was made out of metal in the shape of a bare right foot.

  4. What? The mighty Duo aren’t familiar with the 1999-2000 +.400” extended crankshaft register LS engines? Say it isn’t so!!! 🤣🤣🤣

  5. If your gonna use copper silicone for a gasket u gotta coat both sides let them sit till tacky depending on temperature then tighten them down it won’t blow lol.. I had no money when I was younger lol I perfected it on several turbo cars lol usually sand both surfaces a little it’s all in the prep lol

  6. As much as I love the show and how deeply I miss watching it…. This isn’t enough to get me to pay for the ability to watch it…. I can’t bring myself to indulge the greed of corporate network tv.

  7. Easy Peasy as always!!! You always make it work though!!! Get the JB Weld out. You can still make a solid hit I'm sure of it!!! 🤣🤣🤣🤣🤣🤣🤣🤣🤣

  8. watched a blown picklefork boat with 2 guys on 4th of july get on it and it stood on its prop and twisted and sunk both dead drowned..not a fan of back yard drag racing
