pulley combo

By hilljob from salina,ks on 3/3/2010
Pros:
Fits great and looks good
Cons:
You need longer bolts
Best Uses:
Demolition derby cars
Bottom Line: Yes, I would recommend this to a friend

if you dont run a fan and you are running flat head bolts,you have to countersink the pulley yourself,and you have to buy longer bolts for the lower pulley,but make sure you buy the allen head type as the regular hex head is too big and you cant get a socket on it

Pros:
Removes 50 lbs
Cons:
none
Best Uses:
Short engine spaces
Bottom Line: Yes, I would recommend this to a friend

Used this with the Stewart short pump. Removed all of the factory crapola and saved almost a hundred lbs. and 7-8 inches of engine bay. (weight transfer attained).
