Let's not forget the montecarlo turbo cars too
, not as common as the buicks, but they're out there. I kick myself everytime I think about it, quite some time back a local yard had two complete carbureted turbo buicks, one was a 2bbl the other was a 4bbl, I should have bought them both
. The 301 turbo may be a bit much for the 258 anyway, the sixer would likely be a better candidate. On another note, lol, about a year before I bought a car that would've accepted the turbo buick parts (85 cutlass with a 4.1 buick v6), my dad got rid of the complete turbo set up that was on his 78 Regal sport coupe, day late as always, lol.
