After finishing the year with a best of 1.01 under the F/SA index losing some MPH since the engine was first built, I suspect the short block of being tired I plan to build a new short block and change the trans this winter. Of course I will post pictures as I go, followed with a dyno test with data, followed with a track test. I need to make a decision on the bore size and piston to wall clearance, I think I've got a handle on the bearing clearance from my previous testing. I will be nitrating the crank this time as well.
