cam swap help! 89 renix 4.0L
Posted: January 10th, 2017, 1:03 pm
first off id like to introduce my self my name is frank I live in northern jersey and I have a 89 xj with a 4.0. I currently have a ported throttle body a borla long tube header with a 2.5 cat back exhaust, Volvo 4 hole injectors and a cowl air intake. I just removed the head on the jeep due to the head gasket leaking. machine shop called back today head is done and ready to go. im thinking of pulling the motor and doing a fresh rebuild to the lower end no stroker! the funds wont allow it due to the new baby that we have in the house lol. I daily drive the jeep and wheel it so I was thinking a cam upgrade?
I contacted comp camps and the only cam they offer for the 89 4.0 is a 68-232-4. prob is they don't have springs that will work with my year head due to being the older style and earlier fuel injection. they suggested mopar performance but I cant seem to find spring with specs that will work. I called hesco and there parts guy is out of town, and I called 505 performance and he said his stage 2 cam kit will work. says his cams come from bullet cams and a 500 lift on intake and exhaust seems a lot?
looking for some suggestion if I do the comp cam with mopar springs if someone can point me in the correct direction for springs and everything that will work with it or wait to hear from hesco once there parts guy come back. also looking for it to work on a stock tune. any pointers and suggestion and the most information on this would be great guys thank you so much!
