power steering pulley

[Craig O.]

I have to replace the PS pulley on my 67 L79 AC engine, the bent one reads 3770509 CE and GM5 in separate locations on the front. It also has a woodruff key. no info in the judging manual. have some confusion on the proper pulley. Is this the right one?

Yes, it's the correct one for a C-60 application (but not a non-C-60 L-79). All 1963-74 Corvette power steering pumps used a tapered shaft with a woodruff key.

Joe,
What does the 3770509 power steering pump pulley for an L79 with C60 look like? Is it the pancake style or the cast iron spoke style?
Thanks

It's stamped steel, "pancake" type. It's the same pulley used for 300 HP with power steering.

Re: power steering pulley

Joe,
Thanks for your reply. The AIM UPC N40 page A6 was a little confusing to me. The diagram depicts the cast iron 3 spoke type with 3 different pulley part numbers listed. I had boiled it down to the L79 with C60 using the 3770509 P/S pulley and that that pulley was the pancake type but wasn't sure I was right. Based on your reply I think I have it correct for my application.
Thanks again.
