Default Throttle bodies, bang for the buck?

I've seen some beautiful CNC billet pieces, they do add some bling to the engine compartment, but do they increase performance enough to justify the cost?

I remember an article in MM&FF where they tested various size TB's on a heavily modified SBF. The stock Ford TB outperformed almost all the larger TB's across the majority of the RPM range. Is this also the case with the LSx motors?

That's what I was thinking. I'd just port the stock piece, and polish it inside and out.

But has anyone done Dyno comparisons for the various TB's?

I'd stick with the stocker unless you're upgrading your intake manifold.

If you go with a FAST 90mm manifold, you can't beat a Nick Williams TB...

Just port and polish the stocker. If you are going with the fast 90 intake get the Nick Williams 90mm TB.
