I recently acquired a 1987 IROC Z and was wondering about the emblems. My car has Z28 emblems on the ground effects and the rear bumper has z28. Shouldnt the rear bumper have an IROC emblem?

 

Later model years had the IROC emblems. I don't know what year the switch was made.

 

My 87 Iroc had iroc on the ground effects, but nothing on the rear bumper. It had been repainted, i figured they lost the rear emblem

 

No. The rockers and bumper should read Z28 (IROC-Z should be the badge on the dash). IIRC, that was the case until 88 when IROC became a model and not an option, as it was from 85-87.

The rockers and rear bumper on an 87 should all say Z28. The dash will also say Z28 in red.

 

I might have been more specific: IROC-Z should be part of the badge on the dash. At any rate, 87, all seems in order.

85-87 Irocs had z28 emblems on the rockers and rear bumper.88-90 Irocs had Iroc-z emblems on the rockers and rear bumper.All irocs from 85-90 had a dash emblem that reads z28 with Iroc z underneath.85-89 were red while the 90 was yellow

 

Be sure to read up the Tech Data on the main page also.

 

Thanks for the replies guys.

 

ok i have a 87 whick i think is an iroc-z but my rear bumper decal says Z28 and under it it says 5.7 liter tuned port injection its the same on the ground effects and on the dash there all the same so is it a true iroc then

 

Your car may be an IROC, but an 87 wouldn't be equipped with a 5.7.

im sure it is a iroc-z and yes it is a 350 5.7 it has the tag for it under the hood 87 was the first year for the 5.7 liter with the t-tops

 

You're correct--my bad.

I would have to say your are wrong on that since my car has a 5.7 as well and its an 87. Since you already admitted you were wrong then you are excused
