I optimized a stock throttle body by removing half the shaft for the butterfly and countersinking the butterlfy screws. Then polish the inside.
It made a noticable differenc in my 65, the wife's Taurus (60) and Neal's SVT (60).
I getting closer to spending the 125 to find out if the dyno will confirm our perceived gains.
I just got the go ahead from Neal to modify the one I have, Brian you're next. How's the Weekend look?
