I had a fastman tb given to me and it made no noticeable difference on my
5.2, so I agree with Ray..as always.

Personally, having extensively drag strip (and street) tested a stock 68 mm
throttle body vs. a Fastman ported 68 mm on my 4.7L GC, I'd say save your
money again. On an internally stock motor a larger throttle body doesn't
make any difference. FWIW, I stand by that statement on the 5.2L magnums
as well.
