What do you think of the underdrive pulleys for the LT5 offered by Specialized Racing Products?

While I have not used the product, I have seen them, and they are of very high quality. Very nice machine work and finish.

Got them, have not installed them yet. Requires to much to be removed currently. Rather enjoy a full summer with a working car.

I don't see them adding much power for the headache that is involved. I haven't done it to my mustang (which is most peoples first mod) and I don't plan to on the ZR-1 either.

I have always had a reduction type pulley on all my previuos performance cars. When at the track, my engine typically runs between 3500-7200 rpm for 20 min at a time, so I figure I would be a better candidate than most. Still looking for feedback from others before I go ahead and order parts.
