Thanks John for your comments. I've always appreciated the first and second generation Monte Carlos myself. I have another Round 2 kit to build and just this week purchased another older release with a green car on the box. I'm assuming that it's the 2003 issue you're referencing. I've considered doing a vinyl top on of the two builds but the halo will present a challenge in terms of properly laying it out and finding the right size styrene strips. As for the 402 could you possibly use the AMT '69 Chevelle 396 engine? Overall what challenges the kit may provide are well worth it given the cleanly molded body and well detailed kit.
