How do you know for sure, I have two sets which appear to be Camel Back but not sure. Please help.

fast71 · 07-22-2003, 10:04 PM

this is what you are looking for. I found these at my buddy's junk yard . I was walking and tripped over them in the dirt.

Longhorn Man · 07-22-2003, 10:14 PM

post the casting numbers on here.
Not that they are any better that the new stuff...even the dirt cheap vortecs.

fast71 · 07-22-2003, 10:17 PM

the most common is 461 and 462

lukecp · 07-22-2003, 11:35 PM

The last 3 digits of the casting #'s will be:
461, 462, 492, 041, 186, and i believe 291 was also a casting number. The 492 and 186 heads are pretty desirable b/c they have accessoy holes for alternator and A/C brakets, while the others do not.

And yes, camel hump heads aren't the best hi-performance heads out there, but i love mine. You can still use all the standard intakes, valvecovers, and pushrods for any SBC, and getting a rebuilt pair with a little porting work done is still a couple hundred dollars cheaper than a pair of Dart or World Products heads.

041's have the accessory holes also

RACING29 · 07-23-2003, 08:50 AM

041's are not double hump heads. 041's are the same as 040's. What's a set of 461X heads worth?

lukecp · 07-23-2003, 10:30 AM

You are right.....041's do also have accessory holes. Any head made after 1969 should have them. I am pretty sure Mortec.com listed 041 as a double hump head...even if they dont have the 2 humps on the end of the casting, they still are a 64cc closed chamber head, and some came with factory 2.02/1.60 valves.

461X heads are proably the rarest and most potent double hump head made....the intake runners are 10cc's larger than the standard 461 head...up from 150-something to 160-something i think. I dunno what they are worth though.......

What is it with Camel Backs! Are they the best or what?
Is the idea to put big heads on th 350 block? Very interested!
Cheers

Camel HUMP heads were good at one time, years ago. The newer stuff flows just as good and are more reliable. The Vortex flow the best.

The idea is to run a heads with large ports and big valves, and small closed chambers for added compression.

67chevemall · 07-23-2003, 02:52 PM

Is this what the stroker part of the deal comes from?
Or is it just one of the many heads you can use?

That was 100 !!
Anyone have good avatars!

Na, stroke comes from the size of the crankshaft (and determines how far the pistons travel up and down). The size of the ports and valves in the heads determines how much fuel and air they will flow, and compression pretty much determines how hard the combustion will be (like sticking dynamite in a brick)

Cool Thanks

In a nut shell!

I know now that I have a set of camel back heads, I will have them built and use them on some ptoject. You have been very helpful and it is that which makes the board worthwhile.

I don't know how the pic will turn out, but I hope this helps?
