Thoughts on Holley 670 CFM Throttle Body

[Vortec350S10]

I'm thinking about getting one for my 350. It has vortec heads and a mild cam and I'm wondering if anybody has replaced their stock throttle body with one and what kind of a difference it makes. Thanks.

I just put a holley on my 93 350, but since the holley is made for the earlier models, I will need to splice in an older TPS harness. Otherwise, it seems to run quite a bit better, and it will run like a banshee when I fine tune it. When (if) I get finished, I will post a thread on what I did and how much it helped. Good luck.
