Hemi water pump pulley

I need to find a pulley, a reproduction. I looked at Year One, $230 or so. I know they are low demand, but that seems pretty outrageous. Anyone know of anywhere else these are available?

Thanks...

What is unique about the Hemi pulley ?

What year, and application are you looking for? 66-68 B body hemi water pump pulley is the same as a 383/440 single groove deep water pump pulley.

70. that pulley aligns with the outer groove on the dual groove alternator pulley.

The Street Hemi fan pulley has always been different, probably because of the thicker damper.

As I mention the 66-68 383 440 w/o A/C water pump pulley is the same as the one used on the hemi those years. Here is some information from an online ad for reproduction pulley those years.
66-68 426 Hemi Water Pump Pulley. New reproduction with the same spacing as the original. For use with original thick crank balancer or if using a crate motor must use spacer on crank pulley. Must also use a 64-66 or 67-71 hemi alternator spacer set (spacers are the same, but the housing brackets are different) and Hemi crank pulley. Pulley is painted black. Includes 4 - thin head self locking water pump bolts that are needed for pulley clearance (washers are not required). Replaces original Chrysler pulley part number 1821452. Also fits 66-71 383 and 440 without a/c. Will not work with 69-71 hemi crank pulleys.

The pulley diameter is 6-13/16" (almost 7 inches), depth from mounting to outside of pulley is 2-11/16".
Here is the same seller who also has the 69-71 Hemi water pump pulley. It is specific to the 426 hemi, nothing else and should be the correct one the OP is asking about, since he mentions 1970.
69-71 426 Hemi special water pump pulley. Only fits 69-71 426 Hemi. Same spacing as the original, for cars with or without power steering. Fits cars with original thick harmonic balancer or if a crate motor requires a spacer on the crank pulley. Must also have 66-71 hemi alternator spacers, double pulley alternator and 69-71 hemi crank pulley. The pulley is coated steel and should be painted black before installing.

Does not work with 66-68 hemi crank pulleys.

Reference Chrysler part number 2946716

Matt, where is this from, Bouchillon?

eBay, got it!

66-68 crank pulley is different than the later models and it works with the RB Water pump pulley as mentioned. Additionally PS pump was TRW small with RB pulley.

69 up the Crank pulley, water pump pulley and PS pulley for the Federal pump are all hemi specific. Plus change to the dual groove 059 alternator pulley.
