Iroc Convertibles with 5.7L?

Newbie here with a quick question. Was the 5.7L ever available as a factory option for any year of the Iroc convertibles? I am seeing on the net that ASC did convertible conversions to only four 1987 t-top cars with the 350. Other than that, I am only finding on the net that the Iroc convertibles could be had with the 5.0L. If any of you subject matter experts could confirm it would be greatly appreciated!

Welcome to the site. Your understanding is the same as what I've come to know.

Re: Iroc Convertibles with 5.7L?

Verts ordered by Chevrolet/Pontiac Dealerships using an RPO and VIN there were no 350 Convertibles. Cars that were ordered by Chevrolet/Pontiac and drop shipped to ASC for conversion there are about 200 of those.

I think there is a 5th 350 IROC I ran across.
