Default 90mm vs. 92mm TB

I am curious if there is a difference between a 90mm and 92mm TB on a stock ls3 intake??? It seems to me that there are more 92mm cable TB's out there.

On a stock engine, there is about 0.1hp difference.

On a h/c engine, there is about 0.7hp difference.

Ill just go with either, there really isnt too much difference HP wise IMO. If you can find a 92mm then go for it, any little HP is worth it.

How would a ported 90mm LS3 throttle body compare to a 92mm throttle body.

It's good for a few HP, Torque, and better throttle response by porting. I'm not sure what the differences would be vs a 92mm, but then again you can port that 92mm for better throttle response lol
