Interesting - I wonder just how many LT5s have suffered loss of the guides (I assume this is what happened to your motor in the photo above - the guide was lost, and then the chain wore through the metal beneath it). One of my ZR-1s has 75K miles on it, runs like brand new, but that is the highest mileage I have on a motor - the other two are stroker builds with less than 15K miles on the build - only 4K miles on the other.
How did you discover this worn item? Just lucky? Or was there noise coming from the front end of the engine?
Thanks Sam,
