This has been killin me for a couple of days now...yeah I'm sure it's easy to figure out & such but whatever. Okay I've got a '91 3.1 Liter V6....how many horse power is it? Or at lest what should it be? It seems that no one knows. Just so ya know...I'm horrible with engines & engine sizes & things such as that. Maybe I'm just a retard but I've never seemed to get it. Heh...

As far as i can remeber both the 91 and 92' (a carry over model) had 140 hp at the crank.

Hope that helps you out.

 

140 hp 185 torque
