Which LS2 TB

I bought a used NW TB which has proven unreliable so went back to the oem 78mm TB. This caused a loss of about 35 whp on my A&A equipped 383. By NW recommendation the LS2 TB is the solution.
Am i looking for a "silver blade" or "gold blade" and is there a required adapter harness?
Any other suggestions would be welcomed.

Thanks all!

For a C5, you want the silver blade LS2 throttle body. You'll need an LS1 to LS2 throttle body adapter cable (Amazon). The gold blade is not tuning friendly.

As I suspected. Thanks for the info. I'm hoping to make a purchase from a member on here.
