This looks like a great deal. Someone hurry up and buy it before I give in to myself and drive 3 hours and buy it. Its only three hours do it… No, you don’t need it…. But you want it…. NO!! stop talking to yourself. BUT…. 
Good luck with the sale.
BTW what year Vette do you own?

Merc had a 92 octane req on the original 525SC which was 7.5 CR and 5.5# of boost and 91 octane was ok in it. 89 was pushing it.
I don't see how 87 would be safe unless the boost has been drastically reduced and it looks like it has stock size pulleys on the blower/crank.
