Quote: I guess another wat to put it..."When did the 440-4 and 440+6 share the same rod/balancer part number?"
all years, 69 did not use a rod/ballancer any different than the 69 440 4V, but the 69 did not use the larger rods that the later years did, thats why the 69 package was faster, lighter rods spun faster
69.5 A12 Bee, first purchased in 1976, car 169 on registry
69 Coronet R/T 440/4 spd
69 Coronet 500 Conv H code 383 4bbl/auto
