jeepwm69 7,600 Posted December 21, 2020 There are a couple of guys on bookface who have really built up their 350 Ranchers, and while I've done a couple of mods to my daughters, two more were mentioned last weekend that I thought I'd add here. I've already posted up swapping in a 400AT front diff, which makes the 350 Rancher selectable 4wd. And this will help you set up a "start in gear" feature like the newer machines have, where you can start in gear, but only with the right brake handle held back 07-13 factory disc brakes from a 420 Rancher will bolt right on at the ball joints, giving you much better stopping power (14-up 420 brakes will NOT fit properly) A 400 AT cam and timing chain is a bolt in slight upgrade. Did this when I rebuilt the kid's 350 Rancher engine. I haven't done any of the mods listed below this point, but plan on trying them. Yesterday, courtesy of Jake A-Ron Duncan on bookface, I learned that the 400AT stator and flywheel will bolt in (350 puts out 245W and the 400AT puts out 320W, and the heavier 400AT flywheel gives a bit more rotational mass which supposedly helps low RPM torque) and the 400 head also bolts on and has slightly larger intake port and larger valves. I have an extra engine in the shop that is more or less rebuilt and ready to go, but I think I'll try finding some used 400AT bits to swap onto that one. 4 Share this post Link to post Share on other sites
