Default V6 to V8 Engine swap

hey,
Okay I just bought a 1994 Ford Mustang. The person who had it before me swapped a 5.0 H/O 1994engine in it. Now it mine as well be a GT just with a V6 transmission and frame the only problem is the speedometor reading isnt correct anymore. I was curious as to if anyone in herewas able to get around that before? It there a special tool or something I can get to fine tune it and make its reading correct? Appreciate any help I can get and If you have questions that would help you withyour answer just ask.

a 5.0 with a sixer tranny, wouldnt the torgue rip that tranny up? but anyways for the speedo there should be a speedo gear that you can change so match it with your rear gears and you should be ok. but wait till you get input from other members
