I'm gonna have to disagree with 2.8 V6 assessment...the early 80s ones might have been troublesome, but my parents had a buick century wagon with that motor from 87 and it ran reliably for 125,000 miles, even on my dad's biannual oil-change schedule. The early ones were carburated, maybe the ironed out the kinks by the time the fuel-injected ones rolled out. Until I read this post I honestly thought SBCs were considered great engines, with the exception of the 305. you always hear that old "you can't kill a 350" yarn, and my dad's 170k mile Roadmaster 4-bolt 350 doesnt burn a drop of oil.
