as for the cam..

i reallllllly thought about doing a mild cam in the 4.0....

i didnt need to spend a $$$ on it also its a DD..

i looked in to a comp cam with lifters http://www.compcams.com/Cam_Specs/Ca...x?csid=12&sb=2

also youll need new springs and retainers.. to do everything for the cam was going to be something like $800 if i got 40hp and 50+ lbs i wood be happy..

its deff something to do..

in your honest opinion, which cam in that list would you say is better in respects for still being a DD and being able to still go off road?

The stock '87-'95 Jeep 4.0 camshaft is a single pattern cam with the following specs:

Advertised duration int./exh.: 270.0/270.0 deg
Duration @ 0.050" lift int./exh.: 197.0/197.0 deg
Valve lift int./exh.: 0.424"/0.424"
Lobe separation angle: 112 deg
Intake centerline angle: 120 deg
Valve overlap (advertised): 46 deg
IVO: 21.5 deg ATDC (0.050" lift)
IVC: 38.5 deg ABDC
EVO: 22.5 deg BBDC
EVC: 5.5 deg BTDC

for a DD and decent low end i would go with
http://www.crower.com/cgi-bin/detail.cgi?prod_id=44915
or
http://www.crower.com/cgi-bin/detail.cgi?prod_id=44242
if you dont want to be that high in the RPM range.
if your interested i actually have the Crower cam above part # 44242 that ill sell to you, never been used, $140 and ill pay the shipping.

i like the sounds of these Crower cams... maybe after i get some other small bills paid off and further down the road this could more than defiantly be an option.

Engine: 4.0 ho

so for i have 96 HO with DUI firepower ignition, 2000 intake manifold with APN header, bored TB, K&N FIPK, summit hiflow cat, borla catback and mines got plenty of sack...
next on my list is 2 1/2 custom s pipe, and some yella terra roller rockers
Personally I'd be careful on what cam you put in the 4.0, I've read that alot of guys have had problems with them..
