Camel Hump Heads

Intake valve sizes on the 461 are 1.94 or 2.02, I do agree with you on one thing, they are great heads.

 

the thing is....the holes are practical because you can bolt stuff to them....so the aftermarket guys always make a point to have 'em.

The first motor in my rod had new style heads with the holes. And my alt mount made use of them. Then we swapped motors to a '70 LT-1 with double hump heads....went to mount up the alternator.....had a head scratching moment.....

 

The '70 should've had accessory holes.

 

The block is a '70. The heads are earlier double humps. 461's.

 

Gotcha.

 

I had a 302 Chevy w/ small valve 461s and a Crane Fireball II cam that was nothin' but fun. With a 4 speed and a light car I could beat the crap out of it but still never get too far out of shape. Ohh, the memories.

 

We used to install 2.05 Buick valves in those heads for circle track racing.

 

Sorry to get off the subject, but what's the truck in your avatar?

 

...had mine machined for 2.05's

 

1939 Studebaker Coupe Express

 

Wild, sure had me stumped.

Yep, anything '68 or newer would have
had the accessory holes. 1967 was the
last year for the 'old style' "no accessory
hole" heads. Since the LT1 didn't come out
until 1970. either someone swapped the
heads for a pair of '67 or older style heads,
or it wasn't an LT1!

I think the 1969 Corvette 350 ci motor with 350 hp was the predesessor (spelling) to the LT-1 for 1970. I'm not sure what all the goodies the '69 motor came with...

 

I cleared this up a few posts back. The block is a '70 LT-1. The heads were earlier double hump 461's.

 

Saw this on another post recently: http://www.castheads.com/disguise_work.php

 

Who needs accessories???? 3 pedals and a stick is all I need.

Very nice smokinbill, have you ran it yet?

 

Just go to the "Tech Archives" and read FWilliams posting about camel humps. Butch/56sedandelivery.

 

They worked then and they work now. Just because something is "New" it doesn't make it better. Just look at the quarter miles times in the 60s and today and I mean street cars. Chevrolet got it right with the 327 and camel heads.

 

After Market Camel Heads would be OK. if there weren't so many Original heads still around. I have this set of 194's nobody wants, fully ported. Good around town and plenty of power to spare.

 

Actually the 65 327-250hp cars did have them.

Ditto on the 250/327 having them. It was
only the 210hp 2bbl 327's that didn't have
them.

This is not correct. the 62-64 250hp had the power pack heads. I have a 63 motor and my friend had a 64 250 hp vette and they both had the 1.72 intake heads.

 

Aerorocket your wrong, mart quoted me if you read my previous post I said 65 "DID" get them and he agreed. You said your buddy ect but your talking 62-64 but missing the 1965 327 250hp introduction ie first year of the double humps on 327-250hp intake1.94/exh1.50

 

Read my post I said 62-64, I do not disagree with you about 65.

 

There the best set of heads for compression and exhaust flow ,I HAVE A QUESTION WHAT ABOUT 307 HEADS............

 

i just dropped my 194s off to be gone through today.they should be done after the new year.they are off my 65 327 300hp motor im pretty excited to get them back.i have another 300hp 327 that is a 67 with the power pack heads on it.dont know weather to keep it or sell it to my buddy.what do you guys think sell or keep.

 

they are on the 292 in my aviator pic
the motor sings
with the 6X2 driving on the centers now i get 16 mpg with out keeping my foot out of it

 

I have Nov. '66 build date 275 hp 327, it came with 461's.

 

I have Mar. '67 build date 275hp 327. It is stock w/ Q-jet and 462 heads (small valves).
