440 Cam

440 Cam - 12/29/09 04:02 AM

I talked to the guy from Summit Racing today about a cam for my car. Currently it's a Non HP 440 out of a 70 Chrysler New Yorker. All is currently stock. I wanted the most Cam I could get without changing the Torque Converter. Springs I don't mind. The Cam in question is a Comp Cam 262270 with a 462470 lift. Rpm is 1300-5600 with a 110 lope seperation. Anyone has this cam and can tell me is this the way to go? I have 3.23 gear and 727 tranny

1970 440 has 10-1 compression. That comp cam is fairly small especially if you have a light car. You can go to Comp Magnum series 270 duration/.470 lift if your car is not over 3600 lbs. Many of the guys here like the Lunati Voodoo cams. I used the Lunati Bracket master II 292/.480-230@.050 in a 66 belvedere 440 with 3.55 gears. It worked good with the low stall converter, however with your 3.23 gear I would stay about 268-270 duration(224@.050). I really like the Comp cams Magnum series cams. I have used their 280/480 cam and loved it. Summit also makes a Summit brand cam that would work. It is 224@.050/465 lift. I ran that cam in a 68 440 in a full size Dodge truck longbed D100 that weighed over 4200 lbs. It ran 14.90 @ 92 mph on street tires spinning the 33-12.50-15 Goodyears

Some good info here, but what kind of car would be a bit of a help too.
Any head work or rock stock?
Manifolds, or headers?
Exhaust system size?
Intake manifold?
Carb? vac sec/ dp?

Generalizing, I don't think you want to go with a cam of any more than 272 advertised duration if running a stock converter. In some situations, that may even be a bit much, The cam you've posted will have nice street manners in most applications.

Not one I'd pick for a tow rig etc..

What are your goals for the vehicle you are putting this in?

The big summit cam or the lunati voodoo 60303 would do you well IMO.

I just want to ride on the highway and cruise. No drag racing but a little street racing with some of the young guys with the chevys...I want good response and good top end.

Re: 440 Cam - 12/29/09 07:14 AM

what's the most cam I can get without changing torque converter for my stock 440? It will have AC if that matters
Posted By: Mr.Yuck

Re: 440 Cam - 12/29/09 01:32 PM

Either Summit cam will work fine and are about 1/2 what the others are. I ran the 488 in a mild 9:1 440 and it worked really well. I did have a 2600 stall and 3.91's...but I have had friends run it in BB with factory stall with no problems.

Re: 440 Cam - 12/29/09 04:00 PM

try a comp cams 21-305-4 magnum replacement. works very well with a stock converter and tall gear, plus has gobbs of torque.

i have the Comp XE268 with stock converter, highway gears(2.76?) in my satellite with basic 440, ~9:1, cast iron heads, HP '69 intake with 650 DP, 1.75 headers to 2.5" exhaust with turbo mufflers and 26.5" tires.

actually gets up and goes pretty well and has great top end since i have the higher geared rear diff.

Does it burn out pretty good with that gear? Cause I have another 2.76 chunk I can put in my rear end. If that gear does burn outs with that cam then I'm putting my 2.76 back in there.

Re: 440 Cam - 12/31/09 03:29 AM

without trying, it'll make some noise...when i finally got the motor in the car and running i just blipped the throttle and spun the tire (open rear) - haven't had a chance to really get out and beat on it since it's winter

Re: 440 Cam - 12/31/09 04:01 AM

kewl! I'll hang on to my 2.76 gear just in case. I currently have the 3.23.
Posted By: scratchnfotraction

Re: 440 Cam - 12/31/09 03:31 PM

if its 8 3/4 and you have 2.76 and a 3.23

IMO,it would only be 30-45 mins to swap them out

I have a 2.76,3.23,3.91 and run the green bearings for fast R&R of the chunks

give me 30 mins and I will let the engine speak

cant be that bad a gear,they run 2.76 in a 300 mph dragsters with 1400 hp

but for a long trip 2.76 are good for mpgs

daily drive the 3.23 is good

strip duty it gets the 3.91

thanks fellas! I am ordering Cam next week from summit. Any input on the SUMK 6400 Cam vs Comp Cams 262270?

Do your math, the only production 440s that had close to that compression was the 67 with (915 heads) & the 6 pack, a "standard" production 70 440 had less then 9.1 comp., pistons sat around .080" too .090" in the hole with 90+ cc 906s.

I would run some 3.23s if you want the best of both worlds, but keep the 2.76s, you'de be surprized at just the difference from these 2 gears, & the 3.23s will still give "loads" of top end with a 440 & bolt-ons. I'm dropping in some 3.73s in my 360 magnum dart that has 2.76s right now, if mine can fry the living "s*it" out of the tires at any speed, i'm sure your 440 will too, if not, you have serious issues , even when i installed some 255/60/15 MTs it'll still cut them loose, not for long though

Re: 440 Cam - 01/01/10 05:20 PM

I run the Crower 32242 with manifolds and 355 rear and the specs are 222 @.50/234@.50 with a wide 112 LSA and good lift too 486/495 with stock rockers and valvetrain, manifolds ect. I run the 32243 in my other car and it goes high 12s with 355 and stock (11.75 ) converter and 4000+ lbs. Both of these cams have great power on the street with tons of low to mid power.

Re: 440 Cam - 01/01/10 05:28 PM

I'll also add that the Crower cams that THESHAKERPROJECT has in his cars don't experience the high-rpm lifter "crash" issues that some of the more mainstream cam companies' "extreme" hydraulics have a well-deserved reputation for.

Re: 440 Cam - 01/01/10 08:11 PM

I'm just curious, how much does a 70 gtx weigh? I'm a big man:6 feet 2 inches and 330pds. Is that a hinderance to burning out? Be Honest fellas.

well, its better burn out than it is to rust but hey, at 330 pounds you might burn out before your time. You wanted honesty.

70gtx will probably trip the scales at about 3800.

From a dead stop I'd say no, since the wheels have to get the weight moving, and more weight is harder to move.
From a roll it probably would be harder to break em loose with more weight though.
Not sure....

Re: 440 Cam - 01/02/10 12:30 AM

turn a corner and gas it in low gear and hold it on the floor till it hits 4500-5000 rpms and shift it

if its got a sg it wont spin much as thats what they are for

if its a one wheel wonder it will smoke one turn around a left or right turn

try that and get back to us

nothing like a dirt road for spinning the tires either

I am about the same size and every thing I got will spin a tire around a corner for sure...I do it often too

What is a sg? My linkage is somehow ferked up. I can only get it in PRND. No drive 1 or 2. The reason is long story. But I have a floor shifter and console to install so all that will be corrected. So only being able to put into regular drive hinders me being able to spin out?

It means that Comp Xtreme hydraulic cams have overly-aggressive closing ramps which limit their RPM potential to well below what smoother hydraulic profiles are capable of.

It's not just a "Mopar thing" either. I've seen SBC and Pontiac tests w/ those series of cams where the valve train starts to go bonkers anywhere from 5000 RPM on up.

Re: 440 Cam - 01/02/10 02:12 AM

idk i can't verify rpms, since i don't have a tach, but my new motor makes power way higher in the rpm range than it did and with a 650 carb limiting it further...i think my XE268 is supposed to be good to 6200 RPMs, but with a basically stock rebuild, i doubt i'll ever go over 5-5500 RPM.

the XE lifters are supposed to be "ticky" also, which i don't notice either

I thought it was the XE-HL cams that were supposed to be "ticky". My lunati voodoo 60303 is no louder at the engine that my stock cam was.

Re: 440 Cam - 01/02/10 12:47 PM

sg = suregrip in the rear differental

makes both wheels want to spin,which hinders showboating by smoking the tires

its for traction not burn outs,but it will do a burn out with both tires if in good condition and you have enuff engine to do it with

not sure on you shifter problem,but they did come with a 2nd/low gear lock out on the tranz in some cop cars

it bolted to the tranz pan rail to block the shift lever

you could remove it to get all the gears

dont sound like what you got but just in case it some thing to look for if its not getting 2nd and low gear

Re: 440 Cam - 01/02/10 04:09 PM

Ok..Thanks for input thus far. You guys are amazing! Mine has a modified slip posi. The guy did something inside to make it do that when xtra torque applied. However,440 BB still should burn out tires in a 3800 pd Satellite so I've been told.
Posted By: landon1

Re: 440 Cam - 01/02/10 04:36 PM

definitely...the old worn out caved-in lifter smogger motor i rebuilt would do a one wheel strip 50' prior to the rebuild
Posted By: scratchnfotraction

Re: 440 Cam - 01/02/10 04:41 PM

never heard of a mod to make one slip with too much HP

a suregrip is a limeted slip unit already

cone type wear out and slip one tire more when over powerd

there are mods to tighten it up so it wont slip as much..milling the cones and adding springs/shims ect...

you need to check your rear axle to see what you do have and if its a suregrip or not

if its an 8 3/4 what chunk is it? 714-742-489???

they also have a suregrip that used clutches and the can be replaced when worn

dont know what he would have done,but to make one slip when over powerd is not something I would do if it was possiable

did he add a locker maybe?
