I have owned quite a few original 70 Six Pak Cars and the earliest I have owned was a F8 Challenger R/T Sept 13th build date. It had a cast iorn intake. The cast date on the intake was July 27 69. I also had a 70 Six Pak Cuda Built at the LA plant on Oct 69. Red On Red. It was cast iorn too. It is on Ebay right now. You know talking to Al Nichols who is since departed us he was Chryslers carb engineer and tuning guru. RIP Al. He told me that on the 69 1/2 cars. Edelbrock and Holley could not make enough Intakes and carbs. I have TCB Bulletins stating that Holley was rushing these out so fast that the metering block air passages were not drilled all the way thru thus cars not idling and hard starts. If you want My Honest Opinion with all my experience parting out a zillion of these cars dating back to 1976 and owning a ton of these cars back then and had the pleasure of dealing with a lot of Chrysler inside guys over these years. BOB McCurry,Gerry Blake, Al Nichols, Dean Nicopolis, And so on. I would have to say no. They were ready to go into the 70 production year full tilt ahead. The Huber foundry worked all summer long. A lot of guys put these on when they were only around $80.00 that were serious racers to save weight over the cast iorn. The pic is a FC7 Shaker 4 speed 100% Survivor Taken back in the day.

At that point, I would think all 6 pack cars had iron intakes. My recollection was that the aluminum ones were phased out by the latter part of Oct or early November.

....cast Iron,... even most early build cars would have been cast iron, as Chrysler knew it had to ramp up it's own production of the manifold due to Edelbrock's inability to supply the necessary volume perdicted,....exception to the rule would be 1970 Superbird

& the 1970 trans am cars. Trans am 6 packs were aluminum (small block).

I bought my 440 6PAK Roadrunner in May of 1975. Scheduled build date was 12/9/1969; date first sold was 12/23/1969. Nice Christmas present, huh?
Now, a lot can happen in 5 years, but it had an aluminum manifold, with the Chrysler part number, and the manifold was painted the same orange color as the engine.
Until someone comes up with proof otherwise, the aluminum manifold stays on.

rftroy, What plant was your RR assembled at? I'd bet Lynch Rd.
I'd bet Lynch Road also.
I'm definitely an E body guy, and I've got a lot to learn about B bodies before I do my own 70 roadrunner, so please correct me if I'm wrong...
The E bodes were all built at either Hamtramck or LA plants.
Weren't all the 69 1/2 A12 cars built at Lynch Road? Which means that the Edelbrock aluminum manifolds would be at Lynch Road. Edelbrock was having trouble making enough aluminum manifolds for 69 1/2 production, which is why Chrysler had to make the cast iron ones. With Edelbrock having problems keeping up, isn't it likely that at least one shipment of aluminum intakes arrived at the Lynch Road plant after 69 production came to a stop in July?
But those aluminum intakes wouldn't have arrived at the wrong plant. If the aluminum intakes were only used at Lynch Road, then leftover aluminum intakes would only be on Lynch Road cars right? No point in shipping leftover parts to a different plant when you can use them right where they're at. Especially if you've got a new supply of Iron intakes you can send to the other plants.
So then, Wouldn't all of this boil down to No Challengers or Barracudas built with aluminum intakes?
What do you guys think? Has anyone seen a 440-6 E body that appeared to have an original aluminum intake?

Can anyone shed any light as to why two different (at least the casting # is different) cast iron 6 barrel intakes were made? Sorry, dont have the #s in front of me, but I seem to recall the #s were sequential. One ending with 5 and another with 6.
The cast numbers for 440-6 are 2946275 and 2946276. Both are cast iron. 275 was early model year builds and 276 was late model builds during '70. I wish I knew the reason for the change...
Also, my understanding is that it was A12 cars that used the Edelbrock Al. intakes in '69-'70 which had the cast number 3412046. But... only death and taxes are certain

Thanks for the info. Your telling me what I expected all along. I guess I'm looking for a iron intake cast in late 1969. Thanks to Dartman for the photo...my car is now FC7 again. It was yellow when raced in NHRA stock class.
I remember seeing it out at Harry's shop still wearing original paint...
