We generally consider anything above .180 on the thrust sides at finish bore a good block...
What is your minimum acceptable thickness for a NON-thrust measurement?
I can say that every cyl that has cracked on my stuff has been on the NON thrust side.. every one.. they varied from .125 to .160.. that was 5 cyls on multiple blocks(all 340 blocks at 4.070 bores)
Mr p just curious as to what year 340 blocks did this.I have 2 340 blocks with 7/70 build dates.
