HI Paul,
    Do you think this 93' Ford motor sport throttle body will work on a custom
manifold for my 13b??  It pushed a Mustang to high 12' in the 1/4 mile.  Cheap
too!  The opening is approximately 68-70 mm.  Smooth action, bearings on the end of
the shaft.
Thanks,
Ernesto

70 mm is 2.75 inch /2 = 1.377 almost six square inches of area. Ought to be
good for about 200 HP at 6000 RPM with a well ported 13B  six port.
Try grinding out the partition on the end housings between
the upper and lower ports. You will need pipes about 18 to 22 inches
long about 1.75 dia on the outside and 1.5 inches on the two feeding
the center housing. Unless of course you are going turbo and then you
will have a four port engine. Things become less critical as you can always
jack up the boost a bit.
