Is it a Special 360 ?

Bill, it was developed as a race head and it was never intended to be a production head.

This rumor is amazingly still in circulation for the last 38 years!

It blows me away to be even asked this.
So I guess one more time typing this out can't hurt.... lmao!

The production rumor comes from the Chrysler engineers being turned down to use it as a production head (on the little red truck) and then sneaking it into the dyno room to see if it would pass emmisions on the 360.

It passed emmisions and made great power so well that those who were there couldn't keep there mouths shut. So when the bosses found out, they were pissed that the orders not to bother with the head were ignored so they killed the program idea dead in its tracks.
