emb1230 Posted February 11, 2012 Report Share Posted February 11, 2012 (edited) A lot of GM's not just W's, the Tach will tell you which engine the car has? Kinda interesting for ads without shots of the engine. Edited February 11, 2012 by emb1230 Quote Link to comment Share on other sites More sharing options...

emb1230 Posted February 11, 2012 Author Report Share Posted February 11, 2012 Yep, but one engine has to be a pushrod the other dohc, lol Quote Link to comment Share on other sites More sharing options...
ManicMechanic Posted February 11, 2012 Report Share Posted February 11, 2012 in IROC Camaros, the 5.0s have a 5000 RPM redline while the 5.7s have a 5500 RPM redline. in first gen S10s (1986-88) a 2.8 truck tach will be 6K and the 4.3 tach will be 5K (1988 only)...

94 olds vert Posted February 11, 2012 Report Share Posted February 11, 2012 My CS does not have a red line. It's a DOHC car. Quote Link to comment Share on other sites More sharing options...
tornado_735 Posted February 11, 2012 Report Share Posted February 11, 2012 I've seen a TB without a defined redline. They must have changed it on the newer ones. This one obviously rivals a Vette for top speed Quote Link to comment Share on other sites More sharing options...
outonthetiles Posted February 12, 2012 Report Share Posted February 12, 2012 My parent's 07 TB had no redline on the cluster.. It looked like the one in the pic right above this post. Quote Link to comment Share on other sites More sharing options...

94 olds vert Posted February 12, 2012 Report Share Posted February 12, 2012 My 94s did...6500 RPMs. Or 6750, can't remember... My cluster goes up to 7k with no redline. Quote Link to comment Share on other sites More sharing options...
emb1230 Posted February 12, 2012 Author Report Share Posted February 12, 2012 Another odd one is that the police pkg. gen 1.5 Lumina cluster seems to be based off of the Canada spec cluster. As evident by the "new moon" for empty; "full moon" for full gas gauge and C and H on the temp gauge. Quote Link to comment Share on other sites More sharing options...
Z34guy Posted February 12, 2012 Report Share Posted February 12, 2012 My Dad's 2011 Silverado has no redline on the cluster Quote Link to comment Share on other sites More sharing options...
GnatGoSplat Posted February 13, 2012 Report Share Posted February 13, 2012 Another fun fact, the 88-91 Cutlass UB3 cluster reads redline from the ALDL serial data bus and illuminates the redline segments as appropriate. So you can swap a DOHC cluster into a pushrod car and vice versa, the redline will display correctly. Quote Link to comment Share on other sites More sharing options...

When my car was tuned the red line was set at 7k rpm. The cluster only goes up to 7k rpm. Quote Link to comment Share on other sites More sharing options...
brake Posted February 15, 2012 Report Share Posted February 15, 2012 99 K1500 4.3 had no red line & a 6k tach Quote Link to comment Share on other sites More sharing options...
Addicted2bass Posted February 15, 2012 Report Share Posted February 15, 2012 Jeremy's TB probably has a redline because its a SS model. I don't recall ever seeing a regular model Trailblazer with a redline, most people that buy Trailblazers probably wouldn't know what the hell redline means anyway.

Night Fury Posted February 16, 2012 Report Share Posted February 16, 2012 Speaking of trailblazers, a recall just came out on 06-07 models for the drivers door harness catching fire. Ironically, the same thing happened to the pass rear door harness in my 04. Quote Link to comment Share on other sites More sharing options...
jake91 Posted February 16, 2012 Report Share Posted February 16, 2012 (edited) My cluster goes up to 7k with no redline. my cutlass had a redline at 6500??? it was a 94 like yours?? and nate what do you mean you had yours tuned? 94's are obd1.5 you have to do a obd conversion to tune it. did i miss this?

Jake, I also don't have an analog cluster in my car either. I had a bunch of other things changed in the PCM other than just the red line.
