IROC-Z Gauge cluster?

Hey guys, new member here. I'm a member everywhere else for TBI's so why not here.

I just went to the u pull it yard with my Dad and I found an 89 IrocZ camaro, 350 TPI/700r4 car. motor/trans gone, beatiful body/interior. car had a borg werner 2.77 rear in it.

It had the 140MPH gauge cluster in it so i grabbed it to make some profit (i'm 15 and broke )

it has the manual speedo cable which is normal for 89, but on the tach, the YELLOW line starts at 5000 and the RED line starts at 5500. I thought this was a 1985 only thing?

I'm 80% i remember looking at the door jam and seeing it was a 1989.

Whats the deal with this tach?

Welcome to TGO. Wasn't in my 85 LG4 IROC. I suggest that 350 TPI's were equipped with them.

So, its a 350 TPI only thing? i looked at a couple videos of 350 TPI cars on youtube and most of them have the yellow line that starts at 4500.

The one that's currently in my car came from a 305 TPI.

Re: IROC-Z Gauge cluster?

From what I know all the 350 TPI Cars were equipped with a 5500 redline tach.Other cars that also got a 5500 redline tach were 305 TPI with a 5 speed manual trans and I believe L69 cars also got them

Re: IROC-Z Gauge cluster?

So this is a 350TPI, 305TPI/5speed, and L69 cluster??

I just thought i'd buy it and sell it to an RS/base guy to upgrade or someone who has the 4500 yellow line and wants the 5009. I'd hate to see it get crushed, i thought the 5000yellow 5500 red was like rare or something. lol

thegoodold350, yea i can do that.

my82roc, you have a PM back.
