It can be but that many liters is usually a V8
3400 v6
what size motor do i have in a 1987 GMC safari V6 here is the ben number IGKDMI52IHB5I4494
3.0L V6
That would be a 2.7L
Either a 2.4 I4, a 3.3 V6 or a 3.8 V6
3.8L V6 supercharged.
2700cc so most prob a v6 engine or straight 6 motor
3.0 L Vulcan V6 or a 3.8 L Essex V6
The only motor it came with from the factory is the 4.0 liter - OHV - V6
3.4l or 3400 v6
4cyl. 2.3 L unless it has a v6
it has a 3.0 v6 hp 190
