C camcdaniel1 New member Oct 2, 2007 #1 I have 4.0 in my 95 Wrangler but it has been swapped. Can I determine if it is a HO or not?
Bounty__Hunter Super Moderator Oct 2, 2007 #2 The main difference between HO and non-HO is the head design, and non-HO is pre '91. If it looks like any other 4.0L from a '91+ then it's a HO.
