Popular Post 56LT Posted May 11 Popular Post Share Posted May 11 (edited) Hello, I am working on a 1956 LTH that co-owned by my dad and uncle and spent most of its life hauling logs on Olympic Peninsula in Washington State. It was purchased new by my grandfather in 1956 and he drove it until he retired in 1989. Shortly before he retired it was re-powered with a Big Cam 3 400 Cummins and retains it's triple stick (5-4-2) configuration from the 1950s. It is unrestored and we are in the process of getting it road worthy again.

Popular Post The Heinz Posted Tuesday at 11:31 AM Popular Post Share Posted Tuesday at 11:31 AM Wow, that's a great looking truck for being unrestored! Repowered with a Big Cam, that's an awesome combination of old school transmission and somewhat modern engine in an old Mack! I've had an interest in the west coast logging industries, so this was a real treat to see this Tuesday morning. Welcome aboard! 4 Quote Link to comment https://www.bigmacktrucks.com/topic/76658-new-member-56-lth/#findComment-595892 Share on other sites More sharing options...

tjc transport Posted 9 hours ago Share Posted 9 hours ago so true, but back in those days drivers knew their trucks, did not overdrive their brakes, and weight cops tended to leave loggers on log roads alone 1 1 Quote when you are up to your armpits in alligators, it is hard to remember you only came in to drain the swamp..

56LT Posted 2 hours ago Author Share Posted 2 hours ago (edited) I haven't played with it yet but I think the 2 speed might be an underdrive. I'll have to shift it and see what happens next time I drive it. Some of the logging roads in the Olympic Mountains were quite steep and the original engine wasn't much over 200hp (215, maybe?). He added a turbo a few years after he bought the truck then it stayed like that until the 400 went in about a year before he retired. The Alcoa wheels were also added quite late.
