Underdrive Pullies on a 5.0, worth it?

[5.0 stang]

would underdrive pullies make a big diffrence in a 94 gt

[SpectorV]

5-10hp/tq so about a tenth of a second (not a big difference)

they don't even make that large of a difference, I put those on my 89 and felt no change at all, aside from dimmer lights and slower turn signals when the headlights were on..

o alright then i guess i wont get them for my car i was thinking of gettin some

i had them on my 89 and they were well worth it, I upgraged my alternator to a 3g at the same time though. I went from running 14.10's to 13.7's with them and a little bit of weight reduction.
