i have an engine that was included with my jeep that i have no intention of rebuilding/using, the engine has an edelbrock rb4 intake manifold on it and a holley 600 carb(4160).  they would need to be cleaned up but nothing major.  i figure someone on here would be able to use it if interested, or i could ebay them, i just dont know what they are worth.  i also have some edelrock valve covers off the same engine, they are the old fashioned "finned". thanks

The valve covers are worth a small fortune.  Esp if in good shape.
The R4B depends on condition, but probably no less than 300 unless it's trashed........ also depends a bit if it's got the AMC number on it or not, at least some folks care.

They actually make the Eddy finned valve covers again brand new.  I bought a set a year or two ago for $225 shipped and they are identical to the ones that were impossible to find not all that long ago.

Someone here said "they aren't quite the same", implied they weren't as heavy or something......... but I've never compared them.

I have an old and a new set of the Edelbrock finned covers.  The only difference I can tell is the old ones say "Rambler" inside, the new ones say "AMC".

I agree that a part numbered R4B will start around $300, the one on my AMX I got for $275.  I nave a non-numbered 1970-up that I got for under $200.

448 5731 = R4B Gen II (66-69)

Not a mystery, it's a 1970 intake - exactly what I have.
Here, I flipped the photo of mine so you could read the number without cranking your neck 180 degrees:

I have (3) R4B intakes that all have the AM4485729 part number on them.
One is a '69 and earlier straight out of AMTech. The other 2 are for the '70 and latter engines. I have seen the latter ones with a hand stamped "70" right below the R4B embossment.

Date Posted: Nov/28/2010 at 8:27pm
Note the '70' on mine, and gee, it was on a 1970 engine!  LOL
Oops, since I flipped the photo, I guess you have to crank your neck 180 to see the 70, otherwise, look at it and search for the OL on the intake........

Man, I screwed up again?
Oh, I see - well, the intake said 70 before I flipped the photo, and now it says OL instead of 70......
If I flip the photo back it should once again say 70 unless only part of it flips.....

so this intake is for a 1970??? the only reason why am asking is because i brought a 390 motor and trans complete and the guy told me it had came out of a 1969 AMX. Again if my motor is a 70 or newer it will be better because i would like to put a 401 bottom end it..

well sc397 said he's seen that number on the 1969 manifolds as well...... hard to imagine since normally when there's a physical change, even as simple as bolt hole locations, they change numbers.
Look along the side that bolts to the head - are the middle two holes in a straight line with the other holes, or are the middle two holes "higher" or closer to the edge on each side?

that is why I asked him to post a picture of the bottom side.

People too often get the early and late manifolds confused.  I recently looked at another crossram that was supposed to be an early intake but the bolt holes looked raised to me so I asked the guy who had it to check with an intake gasket. Sure enough, it turned out to be a 70 and up intake and I already have one of those so unless it is a smoking deal, I just don't need two of them.

If it's a straight line, yes, early (pre-1970)
A straight edge will do it, even a yardstick or a ruler. There's enough difference you can see it.

They are cylinder heads and can go on either side so the casting number is on each head on every engine ever made.
 
As already stated, they are in between the valve springs. If you are unsure what a valve spring is, ask a friend who has more experience in these things than it appears that you have.

I guess that is what real man is suppose to do talk dung behind a computer. NICE. And they only reason why i ask a lot of question is because am not familiar with AMC motors! i never play with them so I.

Sir - pull either of the valve covers and take a trouble light and you'll see the numbers.
The casting numbers can tell us what years and sizes the heads were used on. I do agree, the bolts although a bit dirty and not totally clear do appear to be higher than the others.
A chevy person may not know about the differences in the pre-70 engines and the 1970+ engines, even though the 390 covered 69 and 70, there were differences.
You can crawl under the beast and shine a light up between the block and the motor mounts and see the engine size cast into the block where the motor mount brackets bolt up to the block.
Large enough letters it should be pretty clear. If it's a 390, that's the only engine that could be 68/69 OR 70, other sizes, such as 360, 343, etc. will be one or the other.
1970 was sort of a transition year - and the 1970 390 is a ONE YEAR ONLY engine. Although parts interchange, there were differences - intake is one, they physically fit, but the center holes got moved. The 1970 block deck height is different than the 69 390, heads went to a "dog leg" exhaust port and different exhaust manifolds, etc.

Here's an example of an AMC casting number on a head:

No ouch at all.  You don't know what you don't know. 
 
If someone is new to AMCs or engines in general then suggesting to ask a friend who has more experience is good advice.  I wish a hundred times over I had just asked for some help in the past which would have enabled me to avoid the mistakes that we all make when first figuring all this stuff out.  NONE OF US were born with knowledge about this stuff and need to learn it and what better way to learn than from someone with more experience?
 
When a person asks which head the number is on, it is clear that he is new to this stuff as heads are not side specific that I have ever seen so they always have the same number on them on any older engine that I have ever worked on or taken apart.
 
To save time and mistakes, having help from someone with more knowledge or experience  is a good thing.

You guys thanks again for the information. Again Iam no AMC expert. But if i can remember correctly I do remember reading somewhere that AMC had a "valve cover id" tag in which it will give you the basic information of your power plant. When AMX39068 told me about the internal casting number, I didnt know were to find it. Such as chevy were they use external marking such as the famous "double hump" heads.  Pontiac motor division also use external casting, located in the center of the exhaust port marking such as "670",7k3 or the "093." AMX39068 I also know that it does matter which head goes on which side when building a chevy. Put the wrong head on the wrong side and you will throw off you alt,p.s.and a.c. braket. Same goes for a pontiac, the head with the heater hose outlet can only go on the passage side. AMX39068 I am taking your advice and seeking help only on amc, that is way I became a member on this forum. Again am NO AMC EXPERT. people around my age dont even know what a amc, amx, javelin, or rambler even look like.

Yes, the right (passenger) side valve cover should have a metal tag on it to identify build date and engine.  Check out Tom Benvie's post on how to http://theamcforum.com/forum/valve-cover-tag-id_topic5822.html - decode the tag .

Since the tag is easily removed or valve covers swapped between engines, it's not really a definitive method to identify the engine. Casting numbers and the displacement cast into the block are better ways to identify your parts.

None of us started as experts and we all still have a lot to learn.  My response was not meant to be critical rather it was a reflection of past mistakes that I made that someone with more knowledge and experience would have known better to avoid altogether.  Billd's picture prety much said it all and showed you what to look for.
 
The problem with going by the valve cover tag is it is only accurate if it is original which with AMC interchangability may not be the case.  Lots of people switched from painted to chrome valve covers but never changed the tag so be on the lookout for that change as well.
 
On the bright side, all AMC engines pretty much operate the same so learn one and you'll know them all.

like I said I thought AMC only used their ID tag as some sort of casting number. that is way i question were i can find the casting numbers at. Like I said AMC is a dying breed. After all it hard to go to the auto parts store and ask the parts guy for a vaccum wiper motor for a 69 rambler. Only for him to ask whats a rambler? AMX39068 and what you said about having a friend help out finding a valve spring!?!?  I took as downgrading!

Sorry for the miscommunication.  I had stated in a prior post to look between the valve springs for the number so when you cam back once again asking where to find the number I misunderstood adn thought you were still unclear where to find the number that was suggested to look for.
