Hello, new member here...I think I was registered before, but I forgot my handle/pass

I had a 1999 z28 and got amazing results with simple bolt ons. With just a cutout, whisper lid, free mods, shaner throttle body, and an ASP pulley, I made 330rwhp/340rwtq with no tuning!

I'd like similar #s on my new vette. I have the basic intake stuff done, and the exhaust is ordered, but I'm wondering if I'd have similar success with the ASP pulley kit. I think it's just the crank pulley, and like I said, I had no issues with the one on my z28. Think it's worth it to do it on the c5? Any experience with the part? Thanks!
