"Both Patrick and Nikki were a treat to deal with on our recent engine purchase. I love calling somewhere and having zero doubt that the person I am talking to knows their product. Patrick knows Cummins engines very well; you don't get that help from Cummins directly when dealing with B and C series engines." says Dave on Google

"Been a while since I installed the new 4bta engine. Install went well with a few modifications because of a different fuel shutoff solenoid set up. Delivery was prompt and my salesman had everything figured out correctly. Haven’t run the machine that much. Less than 300 hours. Runs very well. Did have it over heat driving up a hill empty. It’s a logging forwarder. It was empty and had no tracks on the machine. So it.." says Dennis on Google

And now for something completely different, yet somewhat similar!! What is the completely different? Well I'm glad you asked, It's the fact that we have a customer up in Canada who owns a company called Yukon Airboats, and the latest version of their airboat will be using (this is the similar part) a 6BTAA230HP 5.9 12 Valve that has been warmed up and given some love from Justin at . Justin gave the injection pump the needed parts and love with some injectors to get this 6B in the 310-325 hp range with around 1000 plus foot pounds of torque! We are so excited to see a 12 Valve 5.9 powering an airboat!!! Look at that crazy overdrive gear box that is direct drive off of the crank, that will soon have prop attached to it!!! This is awesome and we are so thankful to be along for the ride!!

Scout,,, Tis the Season!!
In the passed 2 weeks we have had an influx of Scout calls... and the 4BTAA140HP extended long block that we offer is just the ticket. Finding something fuel friendly, powerful, hood line friendly and different is not easy but here at we specialize in the " different".
We have 3 going out as we speak and I cannot wait to get the pictures to share with you all as they come together!

As always, thank you for having us along for the ride!!
