Default Under drive pulley question,help?

Can someone tell me if an ASP under drive pulley work on a LS1('97-
'04 vette) and an LS6('01-'04,Z06)? Are the pulleys interchangeable? Is there a difference in the pulley from a C5 LS1 vette and a C5 Z06? I have heard 2 different stories and don't know what to believe.
Thanks.

I have one on my 02 ls6. No problems. Came w/ belts. Pulleys are probably the same size.

LS1 or LS6, no difference.

Just make sure the pulley is for a Vette, as they also make the pulley for LSx F-bodies and GTO's..and those ARE different.

For an ASP with 25% under on main belt, and 10% under on a/c, the Goodyear Gatorback #s would be 4060775 (main belt) and 4040410 (a/c belt).
