friend of mine just gave me a 60mm throttle body from an 87 gt. will this do anything for me on my totally stock 86 gt? if it will, would it be a direct bolt on?

i think if im not mis-informed, that the stock tb, from 86-93 are the same, at 55mm.

1986 - Fords new two-piece tuned-runner intake was optimized for maximum torque output at low and midrange rpm. All Ford's 5 liter passenger car engines used the new SEFI system, though CFI remained in service for some truck applications.

1987 - 1993 - In 1987 the upper manifold plenum entrance duct was enlarged to match the 1987's larger throttle body. The lower intake was a carried over from 1986, both it and the revised upper continued unchanged through 1993
