Because of this I was soooo nervous when i did my HPOP STC fitting. I ended up not dropping anything, but was shaking the whole time lol! But it worked, almost. I apparently forgot to tighten the feed tube down and an o-ring. so it just died on me shortly after. All good now tho.I second the recommendation to be careful with the bolts. If you drop one you're in for a lot of work and time if you can't fish it out from the top. I don't know if you can experience a sicker feeling when working on this motor. It really happens a lot and often leads to removing the transmission and rear engine cover as cranking the motor with a bolt in the gears would be sure destruction.
