Thinking about turbo on my/6 again...
I had one of those years ago when I was between/6s and got rid of it, never owned anything GM in my life, soni had no use for it then.
But yeah it would be close except for no Buick turbo was designed to be a truck engine. Maybe one from a Buick 231 would work? I dunno.
From what I have read, it seems like for my purposes one from an engine 2/3-3/4 of the CID of what you have would be better as one "rated" for your size of engine won't spool up until you get way high in the rpm range of the engine, a smaller one will spool up lower, closer to a usable rpm range. I'm not looking for crazy, mostly looking for the "neat-o, hey that's cool" when I pop the hood for others to see but I definitely want it functional
