Whoops!
I should have said "Z51" suspension on my ancient C4 '87 Corvette, now at 255K miles. Never had a head off and still runs great, although it does use a *little*
oil. It gets me to Baji's while the Cobra is still being put back together. Your son's birthday is most important of course, but if you *really* wanted to, you could do both.
