Vega engines I believe had aluminum cylinders, like no liners, so I was told, they weren't worth tearing apart, a junkyard replacement was like $100 back in the day, I went through a couple...
yep, cheap ass GM tried running the piston & rings on an alum bore... the late ones had iron sleeves? (at least the Monza's did) and ran fine... too little too late... it's Rep was ruined by then...
