I was reading on ls1howto.com that sometimes....sometimes? An underdrive pulley might not fit if you have the double roller timing chain. I do have a double roller. The only way I'd imagine knowing if it works or not is after everything is installed and I find that the belt doesn't line up the greatest. I'd hate to figure that out after the fact. Anybody with experience on this?

 

I don't think you want to run the underdrive pulley with the Radix, as it will also underdrive the supercharger. I'd put it in the For Sale section if I were you...it's also NEW and is complete with belts and new bolt.

 

I have access to a smaller pulley for the radix...that's the only reason for interest. I already have a smaller pulley on it anyway. I am sure I will post it for sell by the end of the day.

 

pm me if your looking to sell them, i might be interested. Price?

 

Im assuming you shimmed the oil pump out to run that chain.. I think the pulley has to be machined some where the front main seal rides. For it to work. I think theres pics on LS1Howto.com.
