AMC 360 cam choice 262ex

I'm building a 1990 amc 360 motor for my 1995 Jeep wrangler.
I have been looking at cams and haven't seen a lot on comp cam 262ex.
This is the one I have been looking at.
I have a holly 650, torker intake, headers off a CJ 304, upgraded ignition with a MSD box.
Need help picking a cam out!!

I came to ifsja because nobody give me good help on jeep form/wrangler form. Figurer yall would know about this the best

Cool project, I've never seen an old AMC in a 95 Wrangler. Post some pictures when you get a chance or get it done.

I put a XE262 in my 401. I'm happy with it, it made 340hp @ 4900 rpm, but what I was excited about was the 420 ft/lbs @ 3000 rpm. That's just what I wanted. I'm glad I didn't go bigger. I don't spend much time at 5000 rpm, I'm more interested in torque.

I have an Edelbrock Performer. Your Torker is a higher rpm manifold, and you have less cubes. I sure wouldn't go any bigger on the cam. People here really like the Melling MTA-1 in the 360s. I was really torn about picking the Comp Cams over the Melling. I even bought a Melling, still have it sitting on the shelf. I may try it at some point.

But I don't think the torque curve would be alot better on mine with the Melling, maybe it would. But it I like driving it. I have 3.31 gears, and higher gears would really wake it up.

I'd have to drive my same engine with the Melling to see which one is 'better' for what I do. But I'm happy with it.

I have the torker because it came with it.
I'm looking for low end torque. I'm doing the amc because I want it to be a JEEP not a sbc like every body has told me to do.
my gears right now are 4.88 with a 4banger but I do have and plan 4.10s went I swap.
How is the idle with that 262 and I'm guessing you put spring and all that?

Thanks Caish.

I'd change to a Performer from the Torker if you want torque down lower.

My springs are nothing fancy, stock valve train.

The cam card said it is required to change out springs and push rods and I think guide plates?

you don't need guide plates. springs may not be needed,but are a good idea with the accelerated ramps of that cam. you need to verify lifter preload,coil bind,and ensure the slot on the rocker arm can clear the extra lift (slot length of arm.)


i ran the little lunati voodoo cam,a very similar grind-i heard once the same guy designed these cams for lunati and comp,who knows-and it really gave nothing extra over a performer grind,other than cost,and being ground about 12 degrees off center.

I have looked at that lunati voodoo cams like them too. The 262/268 in just about the some as the 262ex CC. I just like the CC because you can get a whole kit.

I used the xe262 in my 401. Can't comment on how it would be in a 360. You can definitely tell when you get into it's powerband. It takes 1500rpm+ to feel it. Revs out to 5K+ easily. Keep in mind that using Comps springs they will sock you for retainers (& locks too) as the stock ones will not fit. Seems like the angle on the retainer was different or something.... Didn't want to chance the stock spring not being up to snuff. Also, there is some valvetrain noise. Not noticeable with the hood down but open it sounds like the fuel injectors on an '03 f150 we once had. I'd buy it again.

With suggestions from ristow, and the dyno program I've settled on the Melling MTA-1 I posted some simulation dyno graphs in my cam thread.
peaks hp around 5k, but makes torque from below 2k, wish the dyno sim would start lower rpm, after all its a sim.

Comp makes two different XE262 cams.
This is the correct one.
It has a lower peak rpm, and a wider torque band.
Holley 600, single plane, small tube headers, mufflers, 8.5:1 compression.

I have a CC 268 cam in my 360, with Edelbrock Performer intake, 1406 carb, TH400, and 4.88 gears. Even with 1/8-1/4" carbon buildup on the intake valves from bad umbrella seals, the motor was a screamer. I just dropped the motor off to the machine shop to get it cleaned up and punched 30 over, and asked the machinist what he thought of the 268 cam. He got a huge grin and mentioned he loves that cam in the 360. The 262 is a more modern version of the 268 (single pattern vs the 262's dual pattern). If I were to change anything, I'd go with an air gap manifold. BTW, here a video of a cj5 with my same motor setup https://youtu.be/RKmWTLcn3Uw

This year I finally got my Cherokee back on the road. I have the Lunati 64502. Here is the thread with the dyno numbers.

http://www.ifsja.org/forums/vb/showthread.php?t=121315

It will scoot and really screams. There may be better options, but I love what I have for now.
