I've had these for quite awhile and was curious of where they originated from. My guess is early 70's 440 by the cars I had at the time.
Any help would be much appreciated.

Thanks

think the bottom one  , right side  ends in 464 not 484

2532626 = 66-69 b -body   non hp 383
2532464 = 66 -69 C-body  383 2 barrel  -440 non hp

tantop you are correct. RH cast no. is 2532464 and NOT 2532484. As well as your applications you listed and according to the reference you sent.
Thanks Buddy
