    Well , now that my truck seems to be running pretty well (and that's due to some of the help I've gotten on this board ,THANKS AGAIN! ) I really need a speedo that reads up to at least 120 - the 85 mph has to go ! I'd really just like to install a single consolidated setup as the original but I don't recall seeing any stock speedos that read that high in a truck as old as mine (94). Are there any plug and play aftermarket clusters offered for this truck that might even have a tach included? Thanks in advance

    You could have the PCM recalibrated to output 1/2 the speed so that 30 on the guage = 60 on the road. It's a cheap fix.

    Regular old needle gauges are fine for me . I supposed the PCM reprogram idea is OK . Is this something that can be done with LS1 edit? Would still rather have a new cluster . Any suggestions appreciated . I've looked around online and haven't found much but , of course I could be looking in the wrong places .

    You might consider a Tahoe police package instrument cluster. I'm not sure if they had them in 94 thought. I know they have the 95 and up when the dash changed. Top speed was 123 mph so the gauge went higher.

    1992-1994 454SS cluster plugs right in and reads up to 115. I have one in my 1992!

    Try this link instead; that one doesn&#39;t work http://www.simcoltd.com/product_2028.html
    That being said, those gauges are ok, but I don&#39;t want to see an ad for Simco everytime I check my speed.

    Oh my, I need one of those gauge setups for my 93. I guess it&#39;s time to go salvage yard searching.
