That truck has some awesome lines! Can't wait to see it finished up! Well done!

That’s super clean. I’ve always heard DeRale was the best. 4000 cfm should keep any kind of engine cool.

Love the car super clean

[@jameslintz905]

This truck is amazing

What is that track system that runs along the wall, above the toolboxes in your shop?

[@anetworkservice]

Can we use their PWM Assm and run it with the Holley, or can the Holley do the same thing with a heavy duty computer controlled relay?

[@cameronbrandt9415]

Our controller is a full standalone unit and won’t tie into the Holley control

I've heard rumors that you have to upgrade your alternator when you go from having a manual fan to putting an electric fan. Is that true?

[@wrenchaholic_]

If it’s less than 90a I would. Never hurts to have a little extra power especially when you plan to add accessories.

Why didnt you guys just mount a trans cooler to begin with?
