I have a 7.65 8 rib crank pulley, now my question is and it may be stupid, but does ProCharger classify this as their 8" pulley, or is it truly a 7.65"? The reason I ask is I'm trying to get it right for this calculator (below) and it makes a substantial difference. So, the question is which do I enter in the calculator?

Pretty sure the fbody crank pulley is 7.65. They make an 8" crank pulley, but iirc thats for the GTOs

Really? I wonder if it bolts to the ATI balancer pulley?

I think the GTO uses a different pulley setup, I dont think you can use an 8" pulley on an f-body anyhow if I remember.

The GTO crank pulley is a 7.00". We do make an overdrive pulley for the GTO, that is 8.00" in diameter, shown here. http://www.exoticperformanceplus.com...html?item=1938

We have made an overdrive pulley on an F body in the past, shown here. http://www.exoticperformanceplus.com...Car.php?car=42

The GTO pulley is different than the one for the f body. Bob

What would it be to make another overdrive pulley Bob, price wise?
