Ok as some of yall already know Im in the process of finding/building a plow truck and will dub as mudder in off months. My question is how much weaker are the Th350 compared to the Th400? Ive had a 400 and loved it (was built). I can find trucks all day (3/4 ton at that) with the Th350 but its harder to find the Th400 around here. Either way Im gonna build it eventually when it goes out. Are they roughly the same cost to build? I was at $350 with planetary gears also...not including TC. Knew the guy.
