Stock Throttle Body...
Re: Stock Throttle Body... The stock TB is 75 mm at the blade, but necks down to 70mm. The inlet on the manifold is around 75mm so a ported stock TB is the way to go.
You can see pictures of stock & ported on my webshots page.

Re: Stock Throttle Body... I think they are 70mm
A ported TB was worth 3rwhp and 5 rwtq on my bolt on car. LPE did mine, it was smoother inside, the blade shaft and been cut down a good bit and the LPE opened all the way. For the cost I've very happy with it.
This was before Shaner and Jantzer, started offering their ported TB's. If I didn't have a ported TB I'd read up and try either Shaners or Jantzers.
I don't think there is much if any value in a bigger TB compared to a stock ported one for a 346 displacement engine. Most of what I've read about the BBK 80mm is negative. The opening in the LS1/LS6 intake is about 70mm so I don't see how the BBK is really going to gain much.
