Deep Groove Cast Iron Crank Pulley 396 427 454 3899660 - two grooves
 

Hi Friends,

I have the pictured deep groove cast iron big block pulley available here.

3899660 it is used, as found, and is mint as shown. Two grooves.

Original, not a repop or OTC replacement - genuine as leather. Assembly line piece IMHO. Corvette Camaro Chevelle Nova...

Hard to find and rare piece. As found condition, not cleaned or fluffed.

Cheers all,
Anthony

PM sent but have a question....will that work for water pump and power steering ? 1966 Chevelle original pump location and brackets.
If so, I'll get it.

As I understand it with these cast SWP DG pulleys - that a two groove pulley was the fewest grooves available, not sure that they made a single groove one, so, you got this one and if you didn't have PS, then the second groove wasn't utilized...

I suspect this is the one for PS then...

But, anyone else feel free to chime in please.

Cheers all,
Anthony

i belive the 3869978 is for ps thats what is on my 1967 l78 camaro

Ahhhh, so that three groove I just sold then? ;)

So, what application is this one then? Thanks!

No power steering
