Default 95 z28?

I just bought a new 1995 Z28. But the gauge cluster is only a 110 speedo. When I was under the assumption all Z28's had a 150. He said nothing of a aftermarket or swap. So it made me wonder is it a z28? If anyone has like a VIN code or some other way to confirm it other than badging. That would be greatly appreciated. Thank you in advance

Open glovebox. Look at RPO codes. One should be LT1.

-Or-

Look at the 8th digit of the vin. Should be a P if it came stock w/ the LT1.

Also, my buddy's 95 Firebird has the 110 mph speedo w/ the 3.4L.

I got a 94 formula that had a stock 110 speedo. I believe it came with a 110 speedo and not a 150 speedo if the car didn't come factory with z-rated tires

Yep. If the car didn't come from the factory with Z-rated tires you got the 110mph speedometer.

I had a 94 TA and it came with the 110 speedo also. It cut off around 110mph if I remember correctly too. I ended up getting a hypertech programmer to get rid of the limiter and swapped a 155 speedo in it. They only made these cars in 94 & 95 to my knowledge.
