Is a 1986 cutlass supreme a v8?
A 1986 Olds Cutlass supreme can be a V8. It has to motors that
year. a v6-3.8L CARB or a v8-5.0L CARB. So yes it can be a V8 in
that year. If you dont know just look on how many spark plugs there
are, if you have 6 its a V6. if you have 8 you have a V8.. It can
be a diesel also....
