Really need to find out if the pulley on my truck is stock

i guess it has the stock motorcraft belt on it
it has the cage but i read that the cage can still be used with plenty of aftermarket pulleys

it is black and has allen head screw goin around the middle of it

it is prob a little under 9 inches

thanks

 

Sounds Like a old JDM press on style pulley. Stock upper is 2.93 by the way
Stock 7.5
2lb 8
4lb 8.5 and so on

 

Good number you got there LMR2

#2

BTW, I'm a Rusty Wallace fan

 

Thanks and Howd you like the site? I am doing it myself so i am still doing the best i can to manek it look nice.
Ive been 2 since i was 7 and racing go carts. Except for two summers ago when i raced @ Lowes motorspeedway and Rusty's boy was racing with us so they let him be #2 there all summer so i just went with my favorite Cup driver Tony Stewart's number.

 

The stock lower is gold color center with a huge rubber coupling to the outer ring. Aftermarkets are all billet aluminum. Stock is 7.75" approximately. The most a stock belt will fit is a 2# aftermarket.
