I was drafted into the Army in October 1972 so not sure what occurred in ‘73-‘75 but Hemi blocks were gone when I came back. When plant was closing in mid 2000s a friend in Production Control asked if I was interested in some old files and gave me a copy of the plant Gross Production Record sheet issued in July 1997 (see attached). It lists castings (in 1000s) by year and block (Cu. In. Displacement) since 1961 so it covered Chrysler in-house Hemi block production. This would not cover later outsourced (other Foundries) production. When I returned to the plant from the service the Hemi tooling was also gone. Don’t know it’s status. Hopefully I got this Product Record to attach properly. Happy Veterans Day my brothers and sisters! Tom Kelly


Tom, to the best of your knowledge, did the Indianapolis foundry use this foundry mark? The reason I ask is that I had a set of 1970 Hemi exhaust manifolds with strange casting dates and what appears to be a foundry mark. After a lot of effort could never definitely identify either.

The Indianapolis Foundry only cast gray iron 8 cylinder engine blocks (and disc brake rotors for a short time in 72) in late 60s and 70s. Later Indy cast the iron 4 cylinder blocks, some of the late production Jeep 4.0 liter in-line six and V-6 iron blocks til plant closing in about 2005/6.
Per a Chrysler casting process booklet I received (published in 1974), there were four corporate grey iron Foundries at that time including Indy. Per that document: the Huber Foundry cast iron 6 & 8 Cyl cylinder heads, 6 cylinder blocks & ductile iron crankshafts; the Fostoria Foundry cast Intake Manifolds, Exhaust Manifolds and manual transmission cases used at New Process Gear; last, the Winfield Foundry cast gray iron camshafts and timing gear blanks.
I looked for that casting mark but there were very few product pics in the booklet so couldn’t tell if that was Fostoria’s mark or not.
Also I’m not sure too if other foundries farmed out work to other foundries if they couldn’t meet production requirements but I do know the Indianapolis Foundry had some blocks cast at the International Harvester foundry (later Navistar)also located in Indy. IH poured some 318 blocks during my time at the foundry & my brother had a 1964 Plymouth with a 383 block that had a rivited tag with IH on it when we took it out for rebuild. Tom

tomkelly,

You know/remember if there was any smart coding in the casting numbers? EXAMPLE: 1st so many numbers were the casting plant...

Trying to track down any info on a block and noticed the 1st 4 casting numbers of the block (3577430) happen to be the same as the 1st 4 numbers of the 340 TA Block (3577130TA).

Please advise.

AAR4Fun, sorry I don’t know about part number assignment. Likely a corporate level determination as we were just a component plant. As far as I know, the Chrysler Indianapolis Foundry supplied all of the company’s engine blocks (unmachined castings) at the time.

I haven't read all the posts on this so I'm not sure if anyone made the commit that there were no street hemi blocks cast in 1967?
Anyone have or seen one cast in 1967?

Also wanted to point out that the 7 22 70 on the list should be Wednesday

Don't exist. The '66 castings were still showing up in '68. What I have read is that Chrysler projected they were going to sell considerably more Hemis in '66 than they did and had cast up blocks in '66 based on that projection.

You are correct as far as a rule goes, yes many 10-66 hemi casting found their way into production cars in early 68. But that being said I am going to post an exception. Greg Lane posted a 2-67 cast hemi block that was from a 68 superstock A body on a FB thread.
I have personally never seen another 67 casting outside f this example.

That had to be some kind of specialty one-of-a-kind block. Had it been part of the normal production casting process one would think it would have had friends. There has been just too much investigation on the existence of 1967 castings to allow only this one to surface. It also seems strange that Chrysler would have had an inventory of 1966 castings available in 1967 and then went ahead and cast a 1967 casting? Why?

I do think it is interesting if you run the casting dates of Hemi blocks you'll find that the vast majority were cast on a Monday or a Tuesday. 2-9-67 is a Thursday.

Feb. 9, 1967 and when did they start to build Hemi A Bodies. Did in 1967 Chrysler start thinking about A Body Race Cars and Cast blocks for a future buld a year later. Most of these blocks are long gone from these cars but I know of a Hemi Barracuda and Dart that I believe has its original motor. The Dart is to far from me to look and the Barracuda has dissappeared from the public but is still local with in two hours if that motor is 100 percent original. Did they stamp a VIN in 1968 on a A Body hemi. Any other pictures of numbers and dates on this block. Greg Lane post the pictures might have to contact him again..

I had a Dart S/S original blocks and it was cast in 68, can’t remember what month, sold it a year ago and have no idea where it is now.

This is allegedly a Hemi block from a 1968 Hemi car. It was posted on the forum and as such I cannot personally vouch for it's authenticity.

Interesting that 2-12-67 was the SPD for the RO cars. I have never seen an original RO/WO block so I have no idea what the casting dates were, but if anyone has an original RO/WO block maybe there is a connection?

I know of a couple that have these RO WOs 67s and will ask if there motors are original. I would think that there motors should be cast in 1966 but this is Chrysler.

Have no clue. IIRC, it was just posted to demonstrate where the VIN was stamped on the Hemi blocks pre-VIN pad.

Didn't Mopar start stamping the 1968 , not before, blocks with the VIN and in some cases the sequence codes on the rear of the blocks on the driver side on the mating surface that the blocks bolted to and on SOME the 1968 blocks on the bottom of the passenger side blocks on the ear surfaces that the oil pans bolted onto that the 7/16 lower bolts to the tranny went through?
