Back in late 71 or 72, Chrysler engineers were working on a DOHC 426 Hemi. With the cancellation of the Hemi in the line up for 72, only 2 of these experimental engines exist. I read this and I have seen the pictures of this engine(s). Do I have the article? No! I wish I did.I read this back in the eighties.This was an external belt driven DOHC engine.Alot of you are gonna say BS! But trust me on this! They really did have it. Post your whereabouts of who, what where and when.
