Lets talk pulley

I just saw you are getting the underdrive pulley. I just installed mine and made a vid about it.You may have a difficult time installing it if you don't have the correct tools. well at least in my car it was.The ATI pulley has a more narrow opening compared to the oem and may be difficult to get the socket in there. I needed to use a swivel plus extension. Not sure how much room the 370 has

As in the socket outer diameter is too large or the socket wall thickness?

Wall thickness i can grind down, but diameter wise, not sure what I need to do.

From what I understand, install is not an issue, only that I have to get the ATI pulley crankshaft bore machined to match OEM pulley bore size.

Wheres your video?

Tight fit or can it come off by hand?
