    110 MPH speedometer on Z28

    My friend just recently bought a 1994 Chevy Camaro Z28. Its got the 350 ci LT1 engine. It puts out 275 HP and 325 TQ and the speedometer only goes up to 110 MPH. I have A 1994 Firebird Trans AM GT with the same exact engine and everything and puts out the same HP and TQ but my speedometer goes up to 160 MPH. Can anyone tell me whats up with that please?

    Tires.

    Not all Z28's came with Z-rated tires. Those that didn't had a speedo that went only as fast as the tire rating. The computer will limit the top speed also.

    IDK about 2 piece. 2.73 cars did come with a steel DS (vs aluminum for 3.23 cars) but it's all in 1 piece. My 02 was a 2.73 car. Not any more though. Along with 3.73's I went with a stock aluminum DS.

    I know about the top speed limiter as my 96 Z28 vert wouldn't go faster than 118 mph no matter how hard I pushed on the pedal (trust me, I TRIED!). My next door neighbor (who was a GM mechanic) told me that verts were limited to 118 mph regardless of tire type.

    The cars limited to 118 (except the verts?) had 225 tires, correct?

    It was either 225 or 235 wide but they weren't "Z" rated...

    My 96 was limited to 118 even though it had "Z" rated tires because it was a vert...

    Good to know. I bought the 96 new in Jan 97. It was in the summer of that year when I asked my neighbor about it.

    I traded in the vert for the 2002.
