Engine Paint for late model Slant 6?

Not for a 77. That didn't start to the latest of the/6s.
I've noticed that the dupli color Mopar blue of late is way off. I hate to say it but Chevy blue is actually closer to right than what dupli color is passing off as Mopar blue these past couple of years.
I did a /6 and a set of 318 heads earlier this year with it and have been to a couple of swap meets already this year and seen other people's engine parts that were recently painted with it, so not all "my" doing.
Might try some of that bill Hirsch engine paint I haven't yet but have also never heard anything but good comments from those that have. Durable and dead nuts on color.
