165 intake manifold question

trying to see if there are any intake manifold upgrades for the 165 motor and curios if he 185 intake will fit. also what's this stuff about the mustang throttle body? i think it was 78mm. does that actually work. i would love to know. thanks guys

Any bolt on 185 manifold will also fit the 165. However, you have to be careful since they locate the throttle body in a slightly different position.
