So, somewhere around a 1/4" cylinder chamber? Keeping the rings down in the block?
Question for the general population. First I've seen. The rod bolts were twice tacked to the rods, each of them for 4 tacks per rod. Is that some kind of old trick? Also, a what would you do question. Reuse the ARP washer flange nuts, torqued to 40-45 ft lbs? Or use new, which I do have some grade 8 fine thread, washer face stover nuts somewhere around here. If I do reuse the ARP, I'm going to put them on different rod bolts than what they came off of, so at the very least, they wouldn't be locking right back where they had started at.
