Well this isn't making much sense! Why did my '83 get the 145 speedo? I'm sure it was the stock one because it's a Z-28 marked speedo. Cummon guys...we need a few more samples! I'm sure the v-6's all had the 85mph speedo!

That's just crappy design! Why would you put an 85mph speedo in a v8? Doesn't cost anymore for a 145 speedo! Actually costs more to produce several different ones! No wonder GM loses money!

>Wow..so far we really have a lot of speedos that GM used! Rears were pretty much on the low numbered side. I'm still wondering why they used so many different speedos! Doesn't make sense.
>Demon's set-up is the only one that seems off...85 speedo with 2.73's??? 3.73 makes more sense....like Duke's. 2.73's?...you'll probably blow by 85 everytime you step on it! Motor's probably turning 2K at 85! lol!
