Shifting an old 15 speed 3406b caterpillar 

Oh man 😢 this brings back memories of me and my dad trucking grain across the province, that old 3406b just a roaring away, you can hardly even hear your self talk

Love that fucking turbo could listen to that all day long

Straight pipes for the win!

Nice set up on those old style splitters. I’d like to see how you have the airlines set up.

Nice g love the way u shifting and floating through gears with no rush keep it up g💥🦖

Great shifting driver

Ohhhh my god I love that darn CAT🐱 engine singing to me while I float them gears 👍👍👍🙌🙌🙌🙌

Q configuracion de a/r tiene tu turbo ? Y cuantas psi alcanzó me interezaria saberlo .. se oye exelente ese 3406b 👌🏻

Oooooo good nice yeahh

Up Aginst the Dash Now Mash Yee Motor

what model turbo is on that?

This didn't sound like a b-model to me, even with the windows down and the straight pipes, I need to hear the rattle from under the hood
