Is this tachometer for a 6 or 8 cylinder engine? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**Backpayne** · 06-19-2022, 09:47 PM

I'm selling a gauge cluster with factory tach and air gauge, but I'm not sure if this will work with a 6 cylinder or an 8 cylinder? Finding information online is darn near impossible!

Thanks!

Date and gauge panel ( if it's in our series truck) I would put my money on a 6 cylinder.

Model OE 6 makes me guess towards a 6 cylinder tach

I'm assuming a 6 cylinder, too, but I don't want to tell someone the wrong thing.

Here are pictures of the gauge panel:

I could be wrong, but I thought I read somewhere how to make a 6cyl one work with a 8cyl.

If it turns out to be variable or dedicated 6 cyl tach ummmm you got a buyer right here
