what gains could i expect?
What are your experiences with this mod?
Thanks in advance!

Re: Larger throttle Body ? There are some ruff spots on the stock one, I just got done port/polish/epoxy mine, not much larger but it really smoothes it out and makes for less drag and turbulence.

A well ported stock unit will flow 825 to 850cfm. Belive me I do it all the time on the flow bench.
For 600hp, I would rather have 1000cfm, the 850 is good for around 550 or so. (basically as much as most heads/cam cars do.)
