I just did a the short belt mod on my Ls6 motor and couldnt find a clear answer or part number for a belt retaining the stock balancer. After a couple trips to the store, I found the right size at Autozone. The P/N is 522k6, its a Kelly springfield belt. The exact measurement is 6 rib x 52.2 in. Hope this helps somebody.

 

Thanks for the info! I'll be able to direct people here in the future.

 

I'm curious what kind of gain you got by doing this? I'm assuming that it now requires much more effort to turn the steering wheel.

 

i would like a picture to see how it looks.

 

Interested also

 

I am not really doing it to gain power but I did read you can gain up to 7rwhp with this mod. This is for my Rx7 and I dont want to deal with the power steering for now so I went this route. Ill take some pictures of the belt routing when I get a chance.

 

yeah, my Datsun dosent have a power rack, so im going to delte it also, i was thinking i was going to have to run a dead pulley though

 

any pics yet ?
