The Stovebolt Site Forums The Parking Lot Big Bolts Fire truck becoming a tractor

It is a 324 Olds with a New Process 540. My original 550 had a 370. I have a wrecker and a winch truck with a 370 but I am not going to swap them. You can't tell the difference between a 324 and a 370 by looking at them. All 3 of them have 2 speed Eatons.
