no reason to go bigger than 61 or 62.. the intake manifold opening will bottleneck you. mines a 63.

So this is something I am considering aswell, how much of a difference do you notice? any affect on MPG? and total cost is around 90? after returning a t body core?

total cost from thefastman.com is $130 after you return the core, but its worth it. he replaces the shaft with a custom stainless shaft and replaces the blade with a new feathered edge blade. he also smoothes the sensor ports on the TB to prevent whistling and installs a new throttle cable spring. i noticed better throttle response and about 2-3 MPG better after i installed mine...

would it be better to have a bored throttle body on the 97 intake manifold or a bored TB on the 99+ intake Mani?
