85 Wagoneer question.
 

I just bought an 85 jeep wagoneer with 35,000 on a new 2.7L V-6 and i
have a question.This Jeep seems to be unexpectedly gutless.I mean it
runs and starts fine but I can punch it and it`s just plain gutless.I
would be very afraid to even try to pass someone in it really.New
plugs , wires ect. Is this normal?Or where can i start do try to get
some more power?Thanks in advance for any help anyone can give me.
