    I've been looking at '87 IROC's and I've seen some that seem to have Z28 on the rocker panels and some that have IROC-Z. Is this a late production year change as I seem to have seen legit IROC's with Z28 and some with IROC-Z. All the '88's I've seen say IROC-Z.

    Appreciate any insight.

    If I remember correct; 85 through 87 when both the z28 and irocz were available they just said z28 on the rockers. And Iroc's had the irocz door stickers. Starting in 88 when they went to just irocz that was when they added the irocz rocker emblems.

    85-87 Will say Z28 on the rocker panel on the IROCs . 88-90 will say IROC-Z on the rocker.

    Also 85-87 you could get a z28 and a Iroc-z. The z28s had silver ground effects where the Irocs was body color with 16 inch wheels. In 88 the Z28 was dropped you could just the Iroc then.

    Remember it's a 30 year old car hard to say how much could have been or has been changed. I don't think z28 emblem would be correct for an 89 being the last year of z28 was 87 (until 91 anyway). The best way to check if it's an iroc is the sticker in the console. Also only iroc's got a 350 (5.7) engine so if the Vin decodes as a 350 then it has to be an iroc. Also if it decodes as a TPI it has to be an iroc even if it's a 305. No plain Camaro with TPI. The engine code in the Vin is the key for you to know for sure. Remember irocz, was short for international race of Champions z28. On the sticker in the glove box it should have z28 and both b4c IIRC.
