I bought a gauge cluster that was outta v6 because the gauges go higher oil and tach i didnt realize that it was out of a v6 till someone told me i want to know if i can make this tach work if I cant can i get the oil gage out of this one and put it in the one i have also what is the highest tach out there for firebirds with the v8 any help would be great

 

The V6 tach wont work with V8's.

The oil pressure gauge should work. This is the separate gauge with the coolant temperature gauge, right?


The highest factory tach for V8 firebirds goes to 8000 RPM.

 

I stumbled upon a post a while back on a solution to make a v6 tach work for a v8. You have to change out a capictor, try searching for 'tach fixed' and you should come up with it. I haven't tried it myself because I'm going to get the engine running first, but I have the materials.

 

If the Firebird tach has the 6000 rpm reading at 12 o'clock, you can swap the face for one that has the 4500 rpm reading at 12 o'clock. This will limit you to showing a 5000 rpm redline, but it will read correctly throughout the entire range.
Some of the V8 tach faces (the L98 for one) had the 6k mark at 12 o'clock.
