'67 327 pully questions. adding PS

[dmartin1]

1967 327 chevy.

may seem like a dumb question, but are the crank pullys the same as 350?

my engine has the 1 belt single groove pully on the crank and water pump(factory no power steering or ac)

what od i need to do to add spaces to the pullys?

i am adding power steering and eventually an ac compressor(maybe). thanks.

Replaced a crank pulley on my '67 327 as it was dinged. Got a chrome replacement from Summit. You can order 1 or 2 groove.
I believe it's more of the question of the year than the displacement. Earlier ones had a deeper groove and the diameters may be different. May have been a different bolt pattern later, not sure. Check pattern on whatever damper you are using
You can also do a custom set-up. Lots of pulleys are available. You just need to work out what belt length you need and get lots of pulley spacers as you will need them to align the pulleys.
If you buy an AC kit, they usually come with necessary pulleys.
