      Even though I did add those washers to my engine mounts, my oil pan is still pretty scarily close to those bolt heads on the crossmember, I might have to check that out after my diff is put back together, if your wondering what I replaced with the engine rebuild I’ll tell ya.
      New main & crank bearings
      New pistons & rings
      All 5 timing chains replaced
      I think like 3 out of 6 sprockets replaced
      Oil pump
      Oil drive gear
      Water pump
      Rear main seal
      Aluminum thermostat housing upgrade
      Headers & header wrap
      New hydraulic lash adjusters
      Cleaned valves on a lathe with scotchbrite
      Cams were cleaned by a custom shop so I could get a custom grind but they got swarmed with business and wanted to put my cams 3 weeks out so I said no and took them back, finished the project.
      I bought an OTC tool kit for the 4.0 chain kit, it was $211 online.

      Yeah it definitely is, especially with a 5spd. This engine is actually really cool with being able to sit in 2k-3k rpms in the torque band and be able to lug around town and within speed limited areas, from 45mph 5th gear I can double down shift and rip 4K-5k rpms and hit 60 in what feels like almost no time at all :D the tq/hp bands are pretty unique in this engine, even though it was a major pain to do a full rebuild, I definitely like how the cam chains are balanced and designed.
      I definitely over used the half slang word “tho”, although I was very tired and didn’t realize, excuse me for being an idiot on Snapchat. Lol

      My friend Brett has a 2004 SOHC engine in his 94 Explorer sport with the 5 speed on 33" tires. I am sure it would give my 5.0 BII a run for its money!
      The oil pan fitment is a issue with his ttb truck as well, I hear he is going 347 now keeping the a 5 speed manual.........tired of the fitment of the SOHC in the Gen I truck huge notch in the heater box, close to the oil pan, close to the frame, etc
      I commend those who have done it, the SOHC is a great engine underneath all of those chains and plastic bits!
