2004 LM7 5.3-- Anyone know what the stock crank pulley size is? I want to get a smaller blower pulley but need to be sure on this one first. I measured 7.5" but would like mfg. specs if anyone knows or has a link, etc.

Thanks

 

what kinda blower do you have

 

In my sig. bro...Powerdyne BD-11A. Check my times before you judge...

 

i saw the bd11a but had never heard of it, not very familiar with powerdyne

 

ttt Well I went ahead and ordered the 11 lb. pulley and a FMIC anyways, but... Anyone know the exact size?
