Yeah. Im trying not to break anything. The jeep is technically my dads and he bought it to plow snow but im saving my money to buy it off him. I went "mudding" through a little hole in my buddies backyard and my dad got pissed i got it muddy. He thinks im going to break it or im going to do sonething stupid in it.

tell me if this is right, my book says 1988 4.0 had 210 ft lbs of torque at 2100 rpm. in 92 the specs changed to 225 at 4000 rpm. any engine builders out there that can shed some light on this for me? why the big difference, the bore and stroke isn't that much different so is it in the head flow? would I gain a lot by putting the 94 head on my 88? and if so the 4.56 gears would give me 3212 rpm at 65 mph before over drive and that is way under the advertised torque curve for the 94 and over for the 88. in fact the stock 3.55 gears give me 2501 rpm at 65 before over drive but it sure doesn't pull very well there.Originally Posted by 99superjeep01
Your RPMs will be way too high with 31's and 4.56 gears. I run 35's on 4.88 and I'm still a little high. Definitely better off with 4.10 unless you plan on doing more. In which case I'd wait till then instead of spending the money twice.
