Sounds like it's ''cammed out'' nice.

@ttyyttss1 Where did you find the plans to build this engine? I'd love to build one for myself one day.

@Superspermo The real engine may max out at 1000 to 1200 rpm, but they have enough torque to move a mountain. Look for a video of a Holt tractor on here so you can see the full size deal lumbering along. In full scale they are absolutely massive engines.

did you fabricate that yourself?

It's meant to be a low-speed engine. Red line on the real engines is probably somewhere around 1000 rpm. That's the way they built them 80 years ago.

It sounds just like my brother's 1930's Cat No 9 Auto Patrol grader at idle.
