I have heard the term double hump heads since the '60s. I've read it in magazines since the '60s. I seen them for sale since the '60s.


But in the last few years, I see a lot of people looking for camel hump heads.

WHEN did people begin calling the 461 double hump heads camel hump heads?

Does anyone have camel hump heads in an old magazine?

they are the same and not.... the camel hump heads and the double hump heads are the same as seen by the flat at the end of the heads, a double hump. We called them fuelie heads. As for the heads, those double humps, camel humps and fuelie heads could either have 1.94 intake, 1,50 exhaust valves, Or 2.02 1.60 valves. As I remember the 1.94 were as cast, the 2.02s were machined in the chamber to unshoud the bigger valves.

Disclaimer: I have also seen many 2.02 valve heads that were not machined. Maybe they were 1.94 1.50 heads with the bigger 2.02 1.60 valves insalled.

Anyway be very careful when buying any 2.02 fuellie heads, the heads tend to crack between the valve seats.

In my vocabulary the heads have been double hump heads for 50 years.

First time I can remember seeing the other appellation was after joining this forum a few years ago.

I remember first calling the heads double hump and/or fuelie heads. About the same time, I alsoused the term double camel hump as some camels have one hump, some have two.

This would have been in the early, early '60's.

I guess it depends on what part of the country you're from as to what they were called.

I'm with Jim on this. I think the fuelie heads and the double hump heads were the nicknames from long ago and the more recent additions to the hobby misunderstood the nickname was due to two humps on the pad at the end of the head and came up with the twisted camel hump name.

I'll bet no one can find references to "camel hump" heads earlier than 1990. I think with the influx of newbies to the hobby, the term was twisted like newbs do and probably picked up by "experts" in auctions and such and passed as gospel.

I think it is a newb thing like the "so many split windows had their split removed, there are only 400 left", "T-top stands for the T shaped configuration of the top", and "frame off" restorations.

I guess you didn't see post #4?

I am far from being a newb!

Actually, many Camels have no hump at all: An Alpaca and Llama are both Camels. The double-hump "Camel" is actually a Bactrian, wheras the single hump is a Dromedar. So unless you want to call them "Bactrian heads," we should stick to the tried-and-true Hot Rod term "double hump."

You're wrong. I've had my '64 since '84 and even back them I was calling them camel humps because that is what I had heard them called. And that was to differentiate them from the 250 hp heads.

Ah, Lars, Lars, you are sooo good with carbs and distributors, but your knowledge of vertebrate morphology and classification are woefully out of date. Time to get the straight scoop from a taxonomist and systematist like me: Camels are camels, but alpacas and llamas are definitely not camels. True, all these critters are grouped within the scientific Family Camelidae, and as such all are technically referred to as camelids, but camelids are further split into the Tribe Camelini (with humps) while llamas and such are in the Tribe Lamini (without humps).

I’m not sure where this leaves us in naming Chevy heads. The most technically correct way would be to call them “camelini-humped” heads, but I’m not sure anyone’s going to remember that at the next swap meet. I don’t think I’ll ever see a crudely lettered cardboard sign advertising “camelini-humped heads $200.” Better to just call them camel-humps heads like I’ve heard since the 60s.

And if all this isn't enough, let's throw in the single hump heads. Per the website below, casting numbers are 3917290 and 3927185.

And the '63-'64 heads were called "power pack" heads. Let's argue about that!

Gotta' be careful though as the '65 250 hp heads were camel, double or fuelie heads also.

I hear that camels have really bad breath.

jim lockwood

OK, I'll bite. Power Pak heads refer to heads first used back in the '50s.

I remember us pulling into a gas station on the way to California back around 1970. The attendant popped the hood to check the oil and goes, wow! Look at that! A big block with Power Pack heads on it!

It was a factory '65 396 Impala wagon.

Just because someone said it, doesn't make it true. My mother had a tendency to refer to my '63 coupe as a "split tee coupe". She used to refer to friends' late model coupes as "split top" coupes.

There is always someone who will butcher the terminology in an attempt to sound like they know what they are talking about.

MikeM

Correct and and around here, any head with a pyramid on it was a PP head regardless of year.

As I said previously, it depends on your geographical location, what things were called.

When I lived around Chicago in '63, the 409's were called '09's. Imagine that! Not that way in southen Indiana

All high output, cross ram '62 413 MoPars were called "RamChargers". That wasn't correct either.

There's lots of examples of differences of what things were called, depending..................
