I hav the crank pull thats aluminum on my SE.
Its the same size as stock, some places do sell them a little smaller, but thats mostly for the 2.3-2.4s.
The only thing I noticed was the rmp's jump up faster.
And with a standard serpt belt it slips, very bad!
With the Goodyear GatorBack its not sliping or squeeking , thats annoying
The only reason I swaped the pully was my stock was bent(
) and GM wanted like $250-300 for one. The aluminum one was under $150.
Those aluminum one's sure do look flashy though
