Your choice, $20+Shipping. If you see one you need, I can check the #'s.

I know your ad is a month old but I am in need of the three groove crankshaft and water pump pulleys (AC car) for a '68 400/455. They appear to be in the photograph but I am uncertain which they are.

Here is what I have. If you can find the #'s of the ones you need, I may be able to help.

3 groove crank pulleys...1, KB. 2 KS M6S units. 1 KS E6S. and a tweeked 399405 KC.

Water pump 3 groove pulleys, 2 KE H6S units. That is all.

Thanks. Just pulled the part numbers from the GM parts catalog (not fun):

Water Pump Pulley GR 1.062 Part #399404 or 409807

Crankshaft Pulley GR 0.659 Part #409806

Power Steering Pump Pulley GR 6.655 Part #399406

Unfortunately the alphanumeric part code letters are not in the parts book, only part group category number and part number.

Dave, the ones you need are a 399405 KC crank pulley and a 399404 KF w/p pulley along with the long snout water pump. Any of the 2 groove power steering pumps will work with them as well. Some of the pumps have square topped reservoir, after 70 I think. 68-70 have the round topped reservoir. Here's some pics for reference. Note the engine with belts have the KC and KF pulleys. Hope this helps some.

Thanks a bunch for the pulley numbers and codes!! They have been the pinpoint parts data I need to get the correct parts. I thought it was odd that the 2,451page GM Olds parts book I have was not covering '68 and '69 pulleys but just about everything else. It is a 1983 publication which might be the reason.

Changing to an AC car is no fun. I'm still trying to figure out how and who will do the metal work to change the firewall for the AC/Fan Box.

You are quite welcome. Good luck with your project. There may be other pulleys and part #'s
that may work with you app. The pulleys I suggest will work for big blocks 68-76 with a/c.
