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.
