The One -Eighty is my favorite tractor of the AC  line up - luv them as they were a light tractor with a sweet 301 ci- engine and a Roosa injector pump that was easy to get power out of,, lets hear some experience of pulling,,

I've been a fan of Dennis and Alan Brabec (NW Iowa) for more than 50 years. In their early years the weight class was 5000 lbs. That was a struggle to make and keep good balance. Next, the weight class became 5200 and I think at that time they were to twin-turbo's and tipped the final drives back one hole, moving the front end forward probably 7 or 8 inches. The final weight was 5500 when roll cages were required and by then they had gone to three turbo's. Each turbo doubled as the air moved along. Top turbo made 35 psi boost. Second turbo made 70 and bottom turbo made 140 psi boost. They won several NTPA Grand National titles in their long pulling career with the mighty One-Eighty.
