Ok, I could get my tb a taper cut for it for pretty cheap here at a machine shop.
It would keep the same throttle plate.
What would this do for my b?
A little better throttle is always nice....I just want to know is it a waste of $$
or not?
Is it better just to buy another tb with a bigger bore?

 

youll gain a couple top end HP by doing it but its best to have the intake manifold port matched with the TB and youll see better results..

Kepp the same throttle plate? To go any bigger you need a new plate.

 

I was thinking just a tapered cut. Kindof a funnel effect. Some guy said it helps...

 

ohhh like a bell cut? It helps if you run a open TB. But if you have any kind of intake on it, that defeats the funnel effect.
