Howdy yall! So i got an old rust block of my buddies ive been tearing apart. Scrapped some good parts off it, but crank burnt up good running low on oil. So anyhow i figured its roughly an 86 or 87 block i went in and asked them to mag the thing for cracks and see about boring it up and having them put in the bottom end for me. The guy at the machine shop tells me its been bored over a couple times and thinks itd be a waste to bore it to a 7.3 because he thinks itl cavitate. Gave me the shpeel on electrolysis and blah de blah. He even said hes never bored one over to a 7.3 so what do yall think? Is it foolish to sink 400 bucks in a good year of a 6.9 block if im risking the **** cavitating?
