I believe that one is a later model battery. Probably late 70's into the 80's...

Thanks, that's kinda what I was thinking. It doesn't have AMC moulded into the top like the mid 70's and certainly doesn't resemble an early Clear Power battery other than the white case.

RD 688899 Aluminum Intake manifold. I have 2 of these that are almost identical except one has had 1/4" milled off of the top which makes it look nearlly identical to the Rebel Machine cast iron intake. These are 2 of proposed 5 or 6 famed "TRACO" intake manifolds. With a AMC type of Research and Development part number, I honestly don't think that TRACO had as much to do with it as the folklore would have you think. Neat chunks of Reynolds nonetheless. Both Intakes are of the 70 and up bolt pattern. The real question to me is, which one was developed first the Machine Intake or the Aluminum version of it.. RD10 by Rick Jones, on Flickr RD9 by Rick Jones, on Flickr RD8 by Rick Jones, on Flickr RD5 by Rick Jones, on Flickr RD7 by Rick Jones, on Flickr I wonder what the little Prestolite looking embossment means on the Machine intake. I have seen that insignia on other AMC cast parts before. RM1 by Rick Jones, on Flickr Here is a picture of the two RD688899 Manifolds side by side. I bought the clear coated ond from a swap meet in Detroit. All of the numbers and letters have been ground off but, you can see where they were. I bought the powdercoated one off of epay years ago.

My wild ass guess. These are the prototypes for the Machine manifold. The boys at the AMC skunkworks had these cast for final flow bench / dyno testing. If your only making a dozen or less of something aluminium is the cheaper, faster, less hassle material to chose. Plus far easier to hand tweek then iron. Once everything was figured out and settled on. The patterns and cores with appropriate allowance for iron were made for production. I don't know all the stories / lore that go with these darlings. But it seems to fit in my mind even if it's less glamorous / x-files then the old campfire tales... Your mileage may vary, Grain of salt and all the other general disclaimers apply!

Wow you find the coolest stuff! I have some peterson’s engine annual publications that have many of those pictures and info in them. Not sure what time of year they came out, in the fall i assume, but peterson put them together every year showcasing the new years production engine offerings. I have a few, 1969, 1970, 1973. From my dads collection.

I have had this stuff for years. It just takes me a while to get a wild hare to post it up. Interesting things to me are the changes to the rest of the engines when the 390 came out in mid year '68. Beefed up main caps, change in rear main clearance, oil pan baffle, intake manifold. Also interesting to me is the water jackets are the same between the 390 and 343. No wonder I am able to bore 343's and 360's to 4.155"

In those days horsepower was selling cars. Amc was playing catch up. Amc had economy figured out and could deliver it no problem. But they had to diversify their product to sell more units in the muscle era. Considering their resources they did a remarkable job. You can watch their technology evolve in their iron as they learned and they did learn well. Even today the magic happens on top of the piston and it is some mysterious shit. But i can tell amc engineering knew what was going on. I also believe the people amc entrusted to race their creation had a fair amont of influence in the r &d arena. And just walking into an amc dealership in 71 was completely different experience than the mid sixties, i can remember even as a young child how much amc changed in a few years.
