Complete setup with everything but the Crank pulley, these were pulled from a "built" 250 motor I was going to swap into my truck...but alas, plans changed! I believe this motor was from a 1972 nova, but I cannot confirm the vintage of the brackets, but it was also a non-integrated head.
PN on the small slotted bracket is AAD-2782A01 / 354526
2 Groove WP pulley for a 250 PS setup
PN 355776AX
250 PS pulley (and the pump if you want it). This came from the 69 Impala
PN 3860457CV
These are painted and ready to go, just a bit dusty and crusty
$old!
