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

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 462410 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 
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?

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.

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

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 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.
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
