is this a good cam for a stock 360 with 4 bbl.?

will this cam make more power than the stock cam? i don't know the stock cam spec for a 360.

the engine is for a dodge w200 so most important is torque

thanks

I had that cam in a truck and wasnt happy with it at all. I had better luck with a comp 260he. It pulled a trailer much better, and for some reason got better fuel economy.

comp XE250/XE256 or a lunati voodoo 60400/60401 would suit you better. use comp #901 springs, and ditch the exhaust valve rotators if you have them

Factory cam IIRC is .410 lift, 252 (gross) duration, so yes you're new cam is more agressive but with only 204 duration you won't notice a ton of improvement.

I'd look at the old Engle (Hughes proprietary grind) single pattern which was ~223 @.050 and IIRC around .504 lift on 110 centers, you'll know it's there for sure but it's not radical at all. Engle might still sell it if you refer to the old Hughes .904 grind. Another good slightly milder one (if you can find one) is the old Cam Dynamics 266 which was 216 @.050 and .467 lift on 112 in at 107. 360's don't mind a bit bigger cam but don't go over about 224 @.050, the cams I mentioned here will be about the same off idle as stock power wise but choppier, and you'll definately feel the extra torque through the middle in the passing gear and when you wind it out.

IIRC the stock cam is somewhere between 180-190 degrees@.050" lift

I gotta disagree with 'wize a bit, I think his recommendations are still too big for a 3/4 ton truck that I would guess is in the 4500-5000lb range.

the XE262 worked real well in the stock long block 360 that I home ported the 1.88 heads and ran with an eddie 600, RPM air gap, and headers in my 3950 lb 5th avenue. but I also ran 3.55's with 27" tall tires, a low gear 904, and a MP166K converter, which brake stalled to ~2300 RPM and flashed to about 2700. I wouldn't use any less stall than this with this combo....

if you wanted to go up to something in the [Email]218-224@.050[/Email] range, I'd definitely upgrade to KB107 pistons, or stock pistons and magnum heads. even with the smaller cams I mentioned, the magnum heads would probably be worth another 15-20 HP/tq over standard 360 heads.

The Cam dynamics 266 is a real pussycat cam and that hughes made tremendous upper bottom torque both in stock short block 360's with no downside drivability issues at all, just quickening the ignition curve more than made up for the longer duration. If you calc out the intake closing with the 223 event and a 106 ICL you'll find you still have more effective displacement than EX: a 318 with a stock cam, I plowed 3 feet of snow with a stock 318 4x4.

The longer 360 stroke and the small 1.88 valve (from my experience) wants a bit more cam, it's a bit like the old super duty 455, it wants more cam than you think it does and the payoff at 3000+ and the extra seat to seat doesn't noticably reduce the off-idle drivability. I'd compare the hughes idle/low end manners to the 340 factory magnum cam, which IIRC was alsos the same cam they put in the 360 little red express.

Not to take issue, but by the same token some of the smaller Comp XE grinds I've been experienced with and "fixed" had some detonation issues in hot weather down here in the Carolinas, I'm a little leary of short seat to seat but longer @ .200 hydraulics, especially in port limited motors. I'd be more concerned about that in a heavier car/truck than I would with a bit slower ramp that is longer at .050.

opinions vary though

Seeing our friend is in the Netherlands and he may have thae cam in hand, I'd advise him to try out the Edelbrock (which is likely a repackaged SSI/General Kinetics cam IIRC), you could do a lot worse.

If not, call Tim Goolsby at Bullet cams and have him spec you something....but my guess it'll be something in the 216-223 @.050 range

But if your goal is ultimate stump pulling low end, and not stronger upper bottom through the mid range (220-4800) is your objective, here's a recipie from the Moparts tech archive.

Patrick,

What's the @.050 with the XE262? Isn't it like 214/220 (or bigger)?

Isn't that in the same range I'm calling for? I'd hesitate to go smaller than that cause you'll never feel it over a decently tuned stock 360.

I've seen some bad results with open chamber heads (no quench) and some of the fast rate cams, particularly with tight converters. here in the sun belt the summer gas is not very good, I'm just thinking a heavy truck would like a moderate but not XE fast ramp overall, but like I say, opinions vary!

I run an XE284 grind in my 427 (SBF) Cobra, it's hyper responsive and works well with the adjuxstable valvegear (another common XE complaint you hear is when using OEM stamped rockers) but 500+ hp in 2400 pounds it's hard to load the motor up too hard anyway.

I have new engle ep-18hyd cam, I wasnt planning on selling it but if you could use it I would. I have been saving it for a truck build, but I dont think that will happen anytime soon.
the specs are.
260 adv dur
216 at .050
.458 lift
on a 113lc
has a powerband of
1500-5500

I think it would be a great truck cam, should have plenty of vaccum and probably do ok with emissions with the wider lc.

That's pretty close to the Cam dynamics 266 I mentioned that's cut on a 112.

The Engle 223@.050 I mentioned is a 110 split and is suprisingly tame at idle, but it comes on very strong from the upper bottom on up.
