Ok i have a 1991 z28 ...... i have the freakin 115 speedometer and it seems like every other 91 or 92 z28 out there has the 145... I know you can switch it, but the fact is why dont i have one? and everyone else does? Ok also where would i get one of these to switch over? junk yard? or can i purchase them new online? thanks

 

What engine do you have?? G92??

 

Yah, my ex 86 auto,carb, had one but my 89 TPI does't. What the hell?

 

i have 305 tpi auto... worst of the z28 engine setup... which i want to change soon, im just curiuos as to why i dont have the 145 speedo

 

The 350 cars came with the 145 speedo and I think the 305s with the better cam came with it as well. Mine didn't because I had the 305 with the peanut cam.

 

My '86 LG4 came with the 145. Starting late that year they put in them.

 

ummm... how often are you thinking of needing it?

 

It usually came along with G92 and standard for 350s. So it's not too unusual to not come with it.

 

I think you had to get the Z-rated rubber to get the 145 speedo. My 90 came with 245 z rated rubber and i have the 145 speedo. Look inside your drivers door it should say if your car came with the 245/50 or 235/55 rubber or not.

 

My car came with the 145 MPH speedo and its a 305 TPI w/auto.

 

My 86 IROC with the LB9 305 TPI didnt come with one. Whats up with that? Mark, your LG4 came with one, now thats hosed. Oh well, I'll just swap it out, or not.

 

Mark's isn't the only one, I have the 145 in my 86 LG4 T-A also.
