That's true, less stress on the rods and rod bolts. Less stress transfered to the crank throws... I guess it's good all round. :P

Re: Stroke of a different kind!!

Poked my head up in the bottom end and scoped it out. Yep, bottom skirts have popped off 5 pistons. Been running like that a while so maybe I have a bit more time to make a plan.

Bottom end has over 100k miles. No telling when it started fragging. Bet it was back when I had some hydro-lock issues. Knew I was not going to be lucky enough to skate past that one so easily.
