So does running near 14 psi of boost on an L27 lower end. Very little KR was present...I had up to 3* of it after the PCM conversion, and most of that I think was due to unadjusted parameters. This was one of the reasons why I ran rich on purpose.
Got the entire assembly apart. Guess what? MAIN BEARINGS are toast too. But the cam bearings are fine. So I am uncertain what that knocking sound was, but regardless this engine was well on its way to being trashed.
Crank is turnable, cam can be saved, rods and pistons can be reused, and I can break the glaze on the cylinder walls. Due to some recent changes in budget, I'll rebuild this as an L27 and either shelve it or store it for another time. I think the SSE finally found a new home
