I have heard about chevrolet`s camel hump heads all my life,but have never seen a set up close.How are they different from regular chevy heads?thanks
Small chambers, big valves, big ports. Original equipment on the 327 go fast engines. Oh...and the distinctive casting ID mark on the end, with two humps on top of a rectangle
they come in 1:94 and 2:02 sizes. now with all the new aftermarket heads that are out they are not in that much demand anymore and you can get them pretty cheap. still good for old school stuff like 292 or 301 period correct gasser motors.
I know a guy who milled camel humps into his aluminum heads so he could run his Corvette in a different class for autocross. it's only cheating if you get caught.
....and, years ago, I knew a guy who ground the twin humps OFF of his heads in order to pass them off as 283 2 bbl heads for stock class drag racing.
I ran across this a few years ago looking for info on my 492 heads: http://www.castheads.com/disguise_work.php Pretty blatant, but...probably goes unnoticed.
They were the thing to have back in the day. Now they are outdated and there's plenty of better alternatives, unless you have other reasons to use them besides performance. Most of them are at the age where guides, seats, valves and most everything needs replacing. By the time that is all paid for, you end up being real close to an aftermarket head that will flow much better and make more power.
Thanks guys.. I have a 64 327/250 with newer heads on it. So now I'm definitely going to grind off the 'new' - to keep with the old!
Yea, thats the ticket! Don't keep anything 'traditional'. Bullshit Great heads! 192's and 202's Larry
1962-65 250 hp 327s had small four barrel carbs (either 4GC or WCFB) and the same heads as the power pack 283s. In that era, the double humps were reserved for the 300 hp and higher 327s.
In Sweden they´re called Mickey Mouse heads. The humps look like Mickey Mouse´s ears. This is a pretty useless post but nevertheless....
Many years ago we had a set of 461 X heads. They came with 2.02s and pretty good sized ports compared to the 461s we had as well. We more or less copied the X port dimensions on the std heads. Put em on a 331 that would sing but the rest of the car was shit. I'd be pretty fond of a pair of them ol heads. Always good power. Newer ain't always kooler, right?
I like to hear small blocks sing... anything from 283's too 331 ci sing pretty good with the right parts...... I remember having a set of those also... I think they came off a '64 327 motor..
This might be what I have. The guy I got the engine from called them "spike" heads. I don't remember what the numbers are.
As was mentioned the 250 327's did not have them also the 210 hp 327 2 barrel camaros did not have them.
Do any of the aftermarket head manufacturers produce a Chevy head without accessory holes or the flat machined pads on the ends? In other words, power pack or camel hump look-a-likes. You would think that there would be a market for good nostalgia motor heads.
