ive have been looking at a supposed 1988 iroc its in good shape and i may trade a firearm for it and by the looks of the car everything says iroc all the correct badging is there the correct coloring and locations with the 5.7 badging and the vin says its a 350 but the speedo only goes to 115 and redlines at 5000 im pretty sure its should be a 145mph and a 5500 redline i cant find a pic of any car with the 115/5.7 combo anyone run into this or did this guy just do a good job of making an iroc i have yet to check the rpo codes

 

Maybe he had a problem with old cluster and this was one that was available and he stuck it in there.

 

RPo codes, if it says z28 it's a iroc, l98 is a 350 car. Lb9 is 305.

he might have put that cluster in as a replacement but would someone go and change a the VIN under the windshield just to make it register as a car that it isnt doesnt seem worth it or did the rs come with a 350 in 88

 

The first place to start documenting a car is the VIN number. The 8th digit is what you're looking for. If you're going to be looking at a lot of Camaros and Firebirds it pays to memorize the engine codes. For 1988 there aren't that many options, S is a 2.8L V6, E is a 5.0L V8 with throttle body injection, F is a 5.0L V8 with tuned port injection, 8 is a 5.7L V8 with tuned port injection.

In 88, you could get a base model Camaro Sport Coupe with the V6, or 305 TBI, and the Iroc with any of the available V8's. The RS was also available in some areas, but essentially it's just a 88 Sport Coupe with a monochrome paint job. The same engines were used in the RS as the base Camaro.

 

i checked the vin and it tells me 5th spot is a p-z28 and the 8th spot is an 8-350. the car also has the rear disc even if its not a real iroc i think im gonna trade my ar-15 for it anyway it is in great shape no rot if its not an iroc ill use it for a donr for my 88 iroc 305 to get that back on the road either way a good investment on my end i believe what would you do in this situation im tired of not driving my camaros im having withdrawals

 

I mean what do guys typically miss when doing a clone i cant find anything else other than the speedo and it seems that would be something you would change to get the whole look. It was the first thing i noticed when i started the car hopefully im reading into this to much and the original was broken and this was just the replacements

 

If the VIN says it's a 350, it's an IROC-Z, end of story. It was the only Camaro available in 1988 with the 350. Who said they replaced the VIN to clone the car? Your post #5 above doesn't make sense. The logical answer to the whole story is that the cluster was replaced at some point. You're trying to think that the car was cloned and built around the only one item that's questionable, the cluster. It makes more sense that since that's the only thing wrong, it was swapped!

 

Picked up that iroc today it is a real one definately worth the trade time to start getting it ready for the spring time
