Got Me some Camel Humps!!

[Rich 5150 69]

Get em done right they are a good set of heads.....port match, unshroud the exhaust valve wall and match all valve heights......( change out seats and valves that are sunk in heads). Mine are on a 406 smblk.

I think I will go with the 268H cam from comp. will it work fine with stock springs on my camel humps?? Assuming they are stock springs.

They should work, but it is always recommended to check for coil bind and retainer to valve stem/seal clearence, when upgrading a cam.

I agree with Captain... always double check. As for cam another thought would be the 279 thumper series from comp cams. It is designed to give ya a racier idle and a decent performance boost with out all the hassle of a large cam. Not downing the 268H cam, as it is a fine little cam, but it is 30 year old tech. The newer designed cam profiles can accomplish a lot more with alot less motor. Just a thought.

There's no tellin what you would get if you typed that in the search
The famed Camel-Hump/Peanut Heads (or fuelie) heads used until '68 had no accessory bolt-holes and used 1.94 or 2.02 intake valves, depending on application. Most camel-hump heads had the 1.94 intake valves.

What kind of heads are these on my 283?

[Captainfab]

The best thing to do is remove a valve cover and get the casting number. All I can tell you from the pics is that they are a '68 and newer head.

If it were me when ever doing a cam swap . I would always buy the cams valve Springs to match said cam as well. It is a peace of mind that is money well invested in your build ... so if you can buy a full cam and lifter set with matching valve Springs. . Also something I have not seen anyone ask you or mention to you is . Do you have power brakes ? Because if you do and you get a cam with a big lope sound that means way less vacuum which means poor brakes if they are power assist. For that you will also want to buy a vacuum can from summit so remember more lope / thump means less ability to stop at lights . Without running a vacuum can .. Happy Truckin

Those look like #416 305 heads.Best to check casting # to be sure tho.If so,they are the 2nd best 305 head available after the L30/305 Vortec head.Casting #059.
Actually,it appears after looking at both pictures that you have 2 different heads.

FWIW,the humps were great heads back in the day & if you're trying be period correct,that's 1 thing,but,if you are looking for performance & efficiency,that's a whole different thing.
A set of L31 Vortec heads,or,any of the similar fastburn heads will be an instant 30 HP over any of the humps.You can make more power with less cam & have much better resistance against detonation.
Unless they have had hardened seats installed,a performance type cam & springs can beat the soft seats out of the head in no time flat.
By the time you have seats installed,install screw in studs & a valve job,you will have a lot of money tied up in a set 50 something year old heads that will be less powerful & efficient.

I'm trying to find the other post - I think by you - where you say something about a good newer head that works good on a 283.

[LostMy65]

Found your other post.

A really good head for the 283/307 is the L30/305 Vortec head.Castin g #059. These are a 58cc head & they will flow approx 220 cfm @ .500 lift with 1.84/1.5 valves.The chambers are not as efficient as the L31 heads, but, they work very good on small inch motors.Just like their big brother, the L31, they will need a Vortec specific intake.

EDIT: Sorry.I missed the part where you got it fixed !!! LOL.

Did anyone catch the age of the thread?

[WOLFMANmike]

the age dont matter to me of this post . because since im still fairly new to the site this post has some good info in it that i my self did not know and now are better equipped when i do my build .. like a for instance the alternator bracket system that does not bolt on the heads . i did not know existed . so im glad that who ever made a comment on this post the site made it look as a new one . or ide never have bumped into this . and got good info

I have a lot of old books that still have good information.
An old thread on camel humps or a new thread on camel humps. Same information.
