The conventional wisdom says that with the deck height in the LT-X motors, running a 6" rod pishes the rings so far to the top of the piston that the top land is a reliability issue under boost. (or nitrous for that matter)


Presumably, 2 pounds of boost would be a non-issue.

By the same token, 20 pounds would be a serious concern.


This begs the question; at what boost level does a 6" rod and it's corresponding spring pack issues become enough of a reliability concern to warrant moving down to a 5.85"(or shorter) rod?


I know there is no hard and fast answer to a question like this, but that's OK. Educated opinions and bitter experience are fine by me.

 

Like you said, no hard and fast rules.
