67 Corvette 427/435 hp BBC Deep Groove Pulleys

[the427king]

Corvette BB never used 3 groove crank pulley..can use dual cast iron ps pulley like a 67 corvette and the 108 is fine, or use a single ps pulley and a triple crank pulley. Much more expensive to go the chevelle camaro 67 BB route than the corvette setup, especially having the 108 pulley already..the corvette double ps pulley has a groove behind the single making the 108 line up. WO power steering on a corvette or chevelle , one of the grooves in the 108 is unused.
