Thanks for the reply. This block and internals had 142k when I took it out. I won’t be reusing anything. I didn’t get a chance to call SCAT or Trick Flow today. My first question for them is will the Icon -11cc pistons that are included in the stroker kit work with the 170 heads or should I piece together the rotating assembly. Worst case I purchase the Trick Flow pistons and wrist pins separately and use scat for the rest of the bottom end.
