I think it's possible the motor could run fine in in current condition if no serious scrapes in the cylinder walls. How do the combustion chambers and plugs look?
The cylinders look okay, no scarring or scrapes. Just the sizable ridge and NO visible cross hatch. Combustion chambers and plugs (AC Delco) were both covered in black soot, like the engine had been running rich. But nothing seriously wrong with them. My buddy said we could lap the valves, install new seals and run them.
The pistons had 702 stamped in the top of them. I can't find any info on them when I googled that number. I didn't have a dial indicator, but at TDC they appear to be down in the hole. Does anyone have an idea on what pistons these are?
