no - the 11,058 number is not complete, I'm sure it is short in the 5-10% range (500-1,000 cars) but using those foundry numbers it shows around twice as many HEMIs were cast VS. the number that ended up in a production car what's the timeline - around what year did the 426 HEMI start to outnumber 392 HEMI in dragster/funny car ranks  and were those cast iron blocks?

All, you're very welcome & glad the Foundry info was of interest. By the way I did finally get my own Hemi. My J code 68 Red Road Runner still has its original drivetrain. I pulled the car from a barn lot in 1982 about 5 miles from my home and still have it. Guess I'll have to climb under it now to check its casting date!
Another bit of info: when the engine blocks were hooked & pulled out of their sand mold to air cool they were put into trays on a mile long cooling conveyor that snaked overhead all around the plant. Once semi cooled, they were set on vibratory conveyors to shake out the core sand from bores, water jackets, etc. Blocks would occasionally fall off the cooling line trays. If it jammed Maintenance men would have to find it & repair the conveyor. Prior to the plant closing in early 2000 or so, a 1978 440 casting was found in a remote area of the cooling line where it caused no jam and lay for years. It was removed & put on display in our training building lobby. When the plant closed, I got to bring it home. If you think a machined cast iron 440 is heavy you should try lifting a rough casting! Tom Thanks Tom for the great info!!!!! Any pics of that rough casted 440?
I'm the CARETAKER of Weinstats '69 440 'cuda registry and have 104 of the 360 cars to date. 84 fastbacks/20 coupes. Always looking for new(REAL M-code) '69 440 'cudas to add to the registry so drop me a note if any are found or known. This isn't a publicly released registry. Thanks, Dave

I believe this block came out of the TX9 H6E4 1971 Hemi Challenger. No other information on the car. This is information that I have picked up over 40 years of collecting this stuff and it could be correct. No name of who owns the car now or even it the car still existes or who owned the block in the past. The time period from around January 19th 1970 to the end of the month of January Chrysler ramped up to cast a lot of Hemi Blocks and I even have a 440-6 block cast at this time. My 1971 Hemi Cudas block in cast in this time period also. It is interesting just trying to figure out what happened at Chrysler in 1971 with E body build. Have a few things figured out and then some other information comes out and you wonder how that fits in. This block is from a 1971 challenger that was listed on the 1990 NHOA hemi vin list. The partial to the car is 1B296087, and the name on the list is from 79-82, and is Christian. It would be awesome if this car is still around. Matt

the closest cast 1/15/68 to assembled 3/12/68 dates I have any info on are ~2-months, but most are much longer - that may be due to size of batches & rate at which they were used was it intentional??  the '66 & 1/68 blocks don't have the raised pad for the VIN stamp I will check again, but I have a 1/15/68 block assembled 24May68 and it has the raised pad for a VIN but it is blank. Vin is in the normal spot for a 68 hemi motor. Dragon Slayer, I may have asked you in the past about the 68 block that you mention, but can you PM me or post the partial vin information off that block. Thank you, Matt
