If you get a ported and polished ls7 off ebay, it might be even better than the plain old ls7.

I'm running the LS2/LS7 silver blade throttle body. They switched to a gold blade in the late 2000's and I don't think those will work with our gen III computers. I think the blade opens the opposite way or something causing electrical problems. So I would look further into that and see what you find out.

But I'm running the Silver Blade and havn't had any problems so far.

Also, the LS2/7 throttle bodies are the same.
