Good 460 cam specs?
I couldn't find the stock specs, but I intended on replacing the timing chain, seals and intake and I thought, why not a cheap slightly above stock cam? I'm putting a Edelbrock 460 intake, with 750 carb and will replace the exhaust to free that up. I'd prefer reliability, so I don't want to go much above a plug & play cam. I've only fiddled with 5.8 size motors, but the 460 type always say 'performance' but thats a relative term. Its probably not worth the effort...
something like this:

I like these cams COMP Cams: Xtreme Energy™
The one you linked seems like a pretty mild cam, will most likely work well for you.

Did you put that cam in a built motor, or something closer to stock like mine?

I've just had good luck with comp cams period. I used one of them xtreme energy ones around when they first came out. Noticable difference in low end torque, engine outlasted the truck. The engine was stock before that.

The cam you've chosen isn't far off from stock. The valve duration is actually less aggressive, but the LSA is a bit tighter.
I don't think it's worth the effort to swap that one out. The XE256H linked above would be a better choice for a stock build, especially with some decent exhaust mods. If you can up the compression ratio of the motor when you do a rebuild, even better.
I think rather than go with that cam, you should buy a nice adjustable timing gear set and set the stock cam timing straight up. You'll get pretty much the same benefits.

All comp cams come with a 5 degree advance built into the cam. I just like to add things that will up the torque as much as possible, until the motor mounts can't take it and I have to make my own 
Another thing I like to do is shave the heads to raise compression, the closer to diesel compression in a gas engine the better

I would like to see where you get that info, I have used many Comp cams, talked to them many times, never seen or heard that.
if you want to adjust the cam timing you have to use some type of adjustment, adjustable gears, off set keys, off set gears.
Personally, I don't like Comp cams, but I am prejudice, I have (had, he is dead now) a personal relationship with John Delong.
Nobody grinds cams like John Delong did, he was the master of cams.
Lower compression and better flow has been proven time and time again to make better power.
Also gasoline becomes an issue these days.
-Enjoy

eh, I can't find the timing info on comp cams sight anymore. I could be wrong. Maybe it was their cams are at 110 degrees and others are at 105 degrees? Don't remember and don't know everything.
I agree stock compression and better flow make better high end power, I build my stuff for max low end power. Higher compressions do have their disadvantages. If you go too high you need a high torque starter to turn it over. Also fuel is an issue, I already have to use octane booster to get my stuff to not ping, since I can't get anything higher then 91 octane here that don't have ethanol. To each their own.
I have never had a problem with any cam I've used, used Isky once and Crane twice and Comp the rest of the times. Again to each their own

With a good combustion chamber design and a decently aggressive cam, there's nothing wrong with moderate compression.
With iron head motors like these though, I'd probably stick around 9:1 compression (MAYBE 9.5), a cam in the mid 210s on duration, and have them clean up the heads as much as they can.
My 78 Corvette is an example of REALLY low compression and good flow. It has no ***** below 2000 rpm, but pulls hard from 2500 - 6000.
My 09 Corvette is an example of high compression and great flow. It pulls from about 1500 rpm up to nearly 7k.
Compression will increase power across the band, increase fuel economy but require a good mind for proper combustion (spark, fuel ratios). Low compression allows you to get lazy with it. Considering these are truck motors and pull loads, we have to be more vigilant about it than with a sports car. Not to mention, most people would balk at putting anything other than 87 octane in the gas tank. Hence my recommendation for ~9:1.

TRY THE SMALLEST COMP CAMS THUMPER CAM,,WILL REALLY WAKE YOUR ENGINE UP IN THE LOW RPM'S,AND YOU DON'T HAVE TO MESS WITH THE VALVE SPRINGS CAUSE THE HAVE AN ADVERTISED .505 INTAKE AND .493 EXHAUST,,,JUST A TAD EXPENSIVE THOUGH!!! AND DON'T FORGET TO USE YOUR ZDDP ADDITIVE WHEN YOU BREAK IN YOUR NEW CAM,,,GOOD LUCK

Hey thanks for the reply I know this is an old thread. I just installed that x4256h in my 460 build. Haven't got to fire it up yet still waiting on funds to finish. I'm debating on pulling it and running the next step up x4262h. Would like a little more lope but don't want to loose all my low end torque to turn the 44s. Got any other cam suggestions?
Another thing is what compression are you looking at? Some large cams will require more compression to operate properly. My Crane cam which is a bit smaller than the X4262H calls for 8.75:1 to 10.50:1 compression due to the timing of when the intake valve closes.
