4.2 carburetor
If you want the best thing going, convert to fuel injection. Howell makes a good throttle body kit that I had on my 87. It started every time. I also installed an hei distributor. Best upgrade I did to my yj. It cost me about $1600 and two days of time on the install. All of the rediculous vacuum lines were removed also. The jeep ran great at sea level or 10,000 feet.
