The S-10 Blazer went quickly; AM on FM tagged it right off the bat. My plan is for things to go a bit slower with this one; you’re going to have to work for it, not just phone it in. And I’m going to give a very rare clue: it shares something in common with that Blazer.
Update: Well, my plan went a bit too well. So while I finish my piece, you’ve got another couple of hours. Easy!
The only thing in common between a blazer and a 70’s or older car is GM’s habit of lopping cylinders off a v8 to make a v6. As the Blazer came with a 4.3 V6 which is a Sbc minus 2 cylinders. So my completely random guess, would be a 60’s Buick or Oldsmobile with the Buick “Fireball” V6.
