NOS GM Original 66 67 68 A.I.R. Smog Pulley 3765427 Corvette
 

Hi Friends,

This is an NOS GM deep groove pulley 3765427 - box was shot but one side and part number tag was saved. It has the original phosphate ? finish still - obviously unused and genuine.

I understand that this is a 1966 / 1967 / 1968 Corvette A.I.R. Smog Pulley.
This pulley was used on CA Big Block cars. In 66 it was used on the L36 (427ci x 390hp) and in 67 it was used on L68 (427ci x 400hp), L71 (427ci x 435) and L89 (427ci x 435hp aluminum heads). Parts book shows 327 as well. This is the add on pulley for the water pump to run the Smog pump belt. It is definitely an original GM NOS pulley, in excellent condition. This pulley is near impossible to find. Even when you buy a complete Smog System this pulley often does not come with it. Here is your chance to purchase an extremely rare part.
