Any of the Olds V8s, as long as they were gas and not deezil.
LOL. You got that right...the "dieselized" Olds 350 was one of the biggest piles of crap to ever come out of Detroit (or any other part of the world).
Pffft. Ran one of those as a work vehicle for a couple of yrs. Long as you didn't burn up any glow plugs trying to get it fired when it got cold, didn't asphyxiate yourself with exhaust fumes until it got warmed up, and allowed yourself 3 miles to get it wound up to pass a Pacer, there was nothing wrong with them. Lol.
