It should be fine, that's what the owners manual probably spec'd when it was new anyways.
Thicker oil than you need will cause higher oil pressure (which can make leaks), higher heat, and reduced horsepower because of the extra work involved pushing the thick oil through.
I'm running 10w30 Pennzoil and a bottle of ZDDPlus additive on my flat tappet 360.

I read an article about oil weights. It is interesting in that those numbers mean jack at operating temp. Strictly speaking those are for when the engine cool starts. Here is the article http://www.ferrarichat.com/forum/showthread.php?t=136052

That is a very long article, most of which can be ignored if you understand the SAE designations for oil weight and viscosity designations.
There are also some people that have replaced camshafts that would very much disagree with:

Please note that it makes no difference what oil you are using. The 0W-20 Mobil 1 that is SL rated meets the same criteria as that SL rated 10W-30 synthetic or mineral based Pennzoil. That SJ or in particular that SH oil some people are looking for (from their older automotive owners manual) is no where near as good as any SL oil of today. Always use the most currently available, highest rated motor oil, even in the oldest, most worn engine. You may require a thicker grade but just make sure it is SL rated.
I use 10w 40 in my street driven 440. Something to think about is that oils require more non-lubricating additives to achieve wide cold/hot spreads.
In other words, there are lots more additives to produce a 5w-40 oil vs a 5w-20.

May also depend on how tight your motor is to what viscosity oil would be best. Personally I don't like most 10W-30's in a high performance motor during extreme summer temps and long trips. I'd use 10w-40 in the summer and 10w-30 in the winter or possibly 5W-30 if you drove your car alot below 32 degrees. 5W-30 is easier on cold startups in winter.

I've always just ran 10w-30 and my 440's been fine. Then again I'm running a stock engine. Add in a more aggressive camshaft lobe design and higher spring pressures and all the sudden lubrication is more critical.
As far as thickness goes, 10w-30 is fine so long as you are able to maintain good oil pressure with it. If oil pressure is too low with the 10-30, step up a grade.
Now for lubricant contents, zinc is more crucial to have in a more aggressive than stock setup as well. I hear people adding in a bottle of the red STP, GM's EOS or whatever they call their newest forumula of it, and other products that are heavy in ZDDP to provide proper camshaft protection with newer oils.
The diesel oils are supposed to have more zinc in them, but I have a hard time finding them in anything thinner than 15w-40, and that's too thick for me.

I run Brad Penn 10w30 Racing Oil in my 383,it has ZDDP in it.So far so good,lots of oil pressure when hot.

I'm now using 20w50 Brad Penn Racing in my Challenger, but haven't decided what to switch to in my Road Runner. It's a mild solid-lifter cam combination that never sees over about 5500 RPM and leads a pretty easy life when driven. Is a quality 10w30 (such as Brad Penn Racing) a good viscosity for this application?
Have you considered AMSOIL AMO 10W-40? It’s a great choice for your flat-tappet camshaft application. It’s formulated with ample amounts of Zinc and Phosphorous and it’s made with 100% synthetic group IV base stocks; Polyalphaolefins(PAO). The PAO base stocks are manmade and are free from the naturally occurring paraffin waxes found in Group II oils which utilize paraffinic crude oil base stocks. Many circles consider this a plus. If you’re going to be driving in colder weather, AMSOIL has a 5W-30 Heavy duty Diesel oil with the same Zinc and Phosphorous levels.
A few things to consider when choosing your next motor oil…
AMO 10W-40 link Zinc and Phosphorous numbers:
Zinc = 1378ppm Phosphorous = 1265ppm
Typical Physical Properties data: Viscosity Index = 178 TBN = 12.1

Wow, that is a fantastic piece of information, thanks! I really appreciate it.
See you guys later, I am headed out to change the 15w50 Mobil 1, I put in the Barracuda LAST weekend!

Is there any advantage using a high zinc content oil in a roller cammed engine or is this only adventageous in a flat tappet configuration?
Only relates to flat tappet cam setups. Rollers don't need to worry. Yet another reason to go roller I guess.
