@@MrREVCHRIS and what kind of preparations or additional mods need to be done when attempting to perform this cam upgrade to an otherwise STOCK jeep xj
Sounds really nice man! Also working with Zack on my 4.7 stroker.. last shop setup the valve seat pressures too high and killed my previous cam after only 2200 miles hence rebuilding again. This time we are running a solid lifter nitrided custom grind (lunati) from 505 perf, fully CNC ported, 8mm valves and springs all done right by Zack @505. Lift is .554 with slightly more duration than the 239-4 your are running to help fill the cylinders of the stroker setup. Tune?
engine is removed from the jeep now due to bearing failure I ordered the parts and i already got it in hands and ill put it together in two weeks time the new stroke will be 4.7 and there will be new videos . in the old setup i was running stock spring and rockers and i was having problems in high rpm
@GeneralTJWillys ''Head was milled .021 there was no problem with the head , I just did that to gain more compression and so far no issues For head gasket i used mopar gasket .043'' make sure you use new valve springs
you can get them from 505performance or hesco i recommend 505 , you can speak with zach , he is very nice and helpful and will direct you with the correct parts.
Nothing but problems with every cam I’ve got from zack at 505. Plus his shipping sucks! Says he shipped it and 3 months later you might get a tracking number. 505 is a joke!
Are you sure that part number (239-4) is correct? The 242 C.I. Straight 6 isn't listed as compatible with that cam. Only some other AMC engines. The part number I got from Comp Cams for my I6 was CC68-232-4
The amount of people in these comments who want this camshaft and that sound, yet ask.. will this work with a stock 4.0 or stock injectors. Guys! No! nothing about this is STOCK! you HAVE TO make other modifications and upgrades, head work, intake, exhaust , throttle body, block work, this list goes on and on, know how to set timing and in a fuel injected application which ain't my thing...I'm going to say no, you're going to have to upgrade injectors and sensors to accommodate this camshaft.
Hey, what are the exact specs on that cam? Did you do lifters and everything too? I'm going for the same power gain/sound as what you got in my ZJ, don't know a whole lot about valve trains. Thanks, bud!
Did you ever have any vacuum issues? I have a 98' XJ with a custom ground Lunati with about the same specs as yours. Mine tends to try and stall in gear at idle and when the brakes are applied. Any input would be awesome, Thanks!
I have watched this video two or three dozen times within the past month. I want this cam so bad. Would this cam cooperate with an otherwise internally stock motor?
I'm going to build my 4.0 Straight Six very soon from where it is now (Stock) and I'm wondering what you had to change besides the cam for this. Springs? Rocker arms, lifters? I'd appreciate a response very much. Thanks!
i was going to ask about the intake but the video was taking forever to load (cellular connection) pretty nice setup, one of the guys in my car club built a stroker to put in a cherokee and put this cam in it, he said it works great, my only question is, which fuel injectors do you recommend running on an '88 with Renix SMPEFI? i'm thinking about going through 5oh motor sports and ordering the bigger injectors, but i'm uncertian as to if that'll work with the cam or not
I've heard with this cam that the lack of vacuum makes the mass airflow sensor dump too much fuel and floods the engine hurting performance. Fine for carbed engines. Are you having any computer issues?
How far did you mill the head and why? Issue? Or just wanted higher compression? Also, how thick was the head gasket you used to finish the job? Thanks. My '05 4.0 needs a new cam thanks to the OPDA issue and was thinking of going with this, or a similar cam for replacement.
The easiest, fastest, cheapest way to raise compression is with a thinner head gasket, but it’ll need to be a high performance reinforced type. They might all be that way nowadays. But he had the head milled 0.021” and while that may seem very slight it doesn’t take much depending on bore and chamber sizes. Also you can’t put the metal back if you went too far. And by too far I mean the valves start hitting the piston or the compression ratio is simply too high and it just spark knocks(dieseling or preignition-intake charge ignites before it is supposed to because of excessively high chamber pressure-like a diesel but at the wrong time and destroys piston over time) even with high octane. And don’t even worry about trying to rely on octane boost. Unless of course it’s a 1/4 mile car only. Generally if they’re doing a performance rebuild they use a higher lift/longer duration camshaft. Of course no free lunches so much great chance of valve to piston interference when the valve is opening so early, moving farther into the chamber, and closing later. If the compression isn’t way too high, but maybe just a little, and there is just a slight interference issue with the valves to piston top, you COULD notch(relief) the top of the pistons with little eyebrow shaped divots to make room for the valve. This also reduces compression ratio a hair. But for one thing, if your cam is that radical, and the compression that high, and you can run 92-93 octane fuel without spark knock, that engine will be very powerful, if it gets enough fuel. From what I understand it’s easy enough to put bigger injectors and higher capacity fuel pump if they aren’t up to task. Give it a fat spark, forged rods, nice pistons and rings, the main caps are known to be very strong, a good harmonic balancer, and rev that baby till the tires become localized pollution, or as I call it, art.
So I need to replace my cam. However on all the comp cam I've seen they say not for fuel injected motors. I read on a forum about needing to reflash the computer. How did you get yours to work?
@@md_randoms2429 I think something may be wrong with your moms jeep, I have 4.10 Gears 35' tires and a turbo'd 4.0 and get around 15MPG, possibly a bad AFR sensor or Coolant sensor putting too much fuel into the engine wasting it I would suspect

Where is this Jeep now after 11 years
this is the coolest thing ive ever heard come out of a jeep
for all you guys that didnt scroll down to see the part number, it is 239-4 comp cams.
That's the best sounding xj I've ever heard. What's the part #?
Comp cams 239-4
@Jacksonkellyfreak what else is needed, jegs website says no stock valve train components so should I just get an edelbrock head?
the cam part no is 239-4 comp cam you can google it
Does it have any other mods that would affect the sound like that? Im subbing if you answer this
I have the same set up, with 24lb injectors, cold air intake, full flowmaster catback exhaust, 62mm throttle body, oil catch can
***** K4r4t3 it's not a custom you can buy it right off the shelf you need the lifters springs and retainers

what size is the cam? and did it trip your check engine light? I couldn't get a good look for lights on your instrument panel?
what kind of comp Cam can do you got in it? it sounds good I got a jeep just like that that I'm trying to cam it up.
How far did you mill the head and why? Issue? Or just wanted higher compression? Also, how thick was the head gasket you used to finish the job? Thanks.
My '05 4.0 needs a new cam thanks to the OPDA issue and was thinking of going with this, or a similar cam for replacement.
So what all did you do to the motor? And would it sound somewhat the same with lets say a borla exhaust? I want to get a comp cam soon.
So on that cam, it says needs more compression, what did you do about that? Did you change the pistons or leave everything stock?
Good eye on that. He said the head is milled which helps a little but between you and me he probably made it a bit more gutless
