aluminum underdrives?
 

is there a big weight difference 'tween aluminum underdrive pullys and the steel ones?

if your looking for ponies, even if a little lighter, i dont think the extra $40 or whatever for alum pullies is worth the extra 1 hp gain, if even that. get the steel, unless your going for looks, then its alum all the way........

I agree with Ghettopop

i ordered the alum. pulleys last nite from blue oval industrys off ebay for 78 bucks shiped. about10 or 15 more than steel and these are powdercoated black. dont care for all the shine under my hood.

I agree with these guys, the lighter the pulley the less stress on the components ( water pump bearings, PS, Alt, etc. )
