Best Cam Selection for more torque and HP ???

Greetings. Im from over in the big tires and lift kit cherokee section, figured I'd swing by here and see what you street cherokee guys have to say about this.........

Ive got a 96, 4.0 5 speed. Im going to clean up and overhaul a low mileage 96 4.0 that has been sitting for a few years. While Ive got it cracked open I am thinking of adding an aftermarket cam for more power. Ive already got intake and exhaust mods done to the maximum. Gonna drop a firepower ignition kit when I drop the new motor in.

WHATS THE MOST POPULAR CAM SELECTION IN HERE?

So how about it? What are you guys running? Any suggestions? thanks.....

I'm still kinda new around here, but I don't think many people run them. I've heard that most people that run aftermarket cams, go back to stock because it causes problems and the hp gains are not very good.

I don't know how much money your planning to spend or how good your mechanics skills are, but you can get a full stroker rebuild for around a grand, including cam, pistons, gaskets, crank, rods, pretty much everything you need for a rebuild/stroke, or you could just get the crank and rods for about 400 and reuse the old parts. You'd prob get a 30 hp gain over a cam for an extra 200.

Just my 2 cents though.

I forgot to add, that sounds like a very very clean jeep man, you got any pics of it?

Thanx man.

Thats about the answer I expected. From everyone Ive talked to, (at least in the 4x4 community) the factory stock H.O. cam grind is about the best you can get while still running the stock guts.

- Anything bigger, you'd better have a stroker combo underneath it.

Oh, well. I'm from the old school of hot rodding. Add a cheap cam, some intake and exhaust mods, go faster. I guess the stout little 4.0 is maxed out until I get serious with a stroker kit. ....still hoping to find an old 258 in the junkyard to donate its guts to my cause.....

Thanx again,

Tom

If you can do the work, you can get a stroker for under a grand.

Hmmm i'm very interested in that mopar cam. You should definantly write a review of the cam. Is there anyone else running one. I would love to see the gains from a performance cam. I would love to be able to gain a few hp with a cam, before having to tear into the engine.

Yeah, from what I am told, the non-H.O. motors have less lift and duration, as well as a more restrictive head. (Renix? I dont know. not familiar.)The cam and head is what supposedly makes the H.O. what it is. Pretty good package for a stock 6 cylinder, if you ask me. All this designed around an almost 60 year old engine design. Given how long its been around and how good it runs, I was surprised there wasnt more aftermarket bolt-on performance upgrades for it.

Doesnt matter, whatever 4.0 you have, its gonna run forever anyway.

I still haven't ordered it, i just ordered a new header and sold my old pacesetter and now I have to debate whether I get a cam or a new motherboard so I can take advantage of the core 2 duo I got on sale. It takes me forever to get anything done..so it still might take awhile lol

New motherboard to support core 2 duo or new cam....hard choice indeed. What model c2d did you get? I'm running an A64 s939 X2 4200+, 2x 1gb ddr400, agp x1950pro, wd raptor 10k rpm 74hdd, 120gb seagate IDE, etc. Yes, I'm a gamer

If you look here http://www.ajeepthing.com/stroker-motor.html you will see what is typically used to compliment a stroker build. I am planning on using the Crane 753905 cam with my build. I know you arent necisarily building a stroker but if you look over the numbers on the diferent build about half of the HP gain can be atributed to the cam and half to the increase in displacement. This does not mean that you can assume you will get 30 HP with it in a stock motor tho.

I'm guessing since you sold it, the pace setter header was a waste of money lol. I was looking at it because of price, and I figured it would be worth a few hp. Did improve your performance at all?

i got the E6420 c2d 2.13ghz 4mb l2 cache 1066 fsb. I thought it would have worked with my current mobo since it is socket 775 but it doesn't . I have a radeon x800 pro (overclocked to 546mhz core and 1107 mhz memory) 1gb ddr 400 ram and a 150gb raptor 10k rpm and 200gb maxtor drive. Thing is with the new motherboard i will have to upgrade ram and videocard since it will be ddr2 and pcie Yes i dabble in gaming too. I really want the cam but now i have a $210 chip (which i paid $160) just sitting here so i don't know

ps. that radeon x1950 is a very good card and is the best for agp
