Went to steeper gears but didn't change speedo

Check my videos. My stock 91 rotating assembly, TFS stage one cam, Edelbrock RPM head, Edelbrock RPM 2 intake and a powerdyne with 7psi and 3.73 gears tops out in fourth gear at 143mph. I do have the dyno sheets and video's. People who talk about that which they no nothing about, should just keep their mouths shut. A completely stock 5.0 motor with 12psi and 3.73 gears will top out at 167+mph in fifth gear. That's a fact I do know.

that car could with that stuff done could not do that. get a new speedo gear then post another vid

thanks for the help by the way

its a t-5 world class, slightly built, just recently actually, but same ratios. tires are 225/50/15s. before i had the cop hit me with radar for top speed, i had another cop do it at 35,45, and 55 mph. at 35 it was accurate within 1 or 2 mph, at 45, it was off by like 5, and 55 it was off by like 8. sais im goin faster than i am. like you said, i just need to get it recalibrated, but i dont have the money lately, so it dont bother me much. just kinda keeps me from getting tickets i guess...ironic, i just got one for the first time in the two years ive had the car
