1969 DOHC HEMI??

[J-440]

 There is a great read in the new edition of Car Craft about the story of Dodge's secret 426 DOHC motor for the NASCAR season.  It seems that Chrysler got wind that Ford was going to unleash it's famed 427 SOHC motor at the start of the season so the boys at Mopar said "If 1 overhead cam is good, then why not 2?"  Well, the engineers did build the motor but no sooner than that, NASCAR told Ford that it couldn't run its exotic 427.  So that being the case, the new HEMI project was scrapped and sold!!  Problem is, no one knows where it went.  This thing is priceless and there are pics of it in the new Car Craft.  Cool story.

Actually I believe they do know where it went.  The one photographed was just a valvetrain test mule or something like that but the photos were leaked to give Bill France nightmares and it worked, he no sooner saw it than he banned the Ford SOHC.  IIRC, Arruza ended up with it didn't he?  There was something recently about it.

I think Arruza ended up with the "Ball stud Hemi". Went into Tom Hoover's A Body Cuda or something like that.

You're right, he got that from Landy didn't he.  I still recall something recently about the Doomsday Hemi, wish I could remember where I saw it.

You are correct Ghoste. The DOHC Hemi never ran. Afterall, it was dubbed something like the "902" Engine program or something. [Code named]
It was purely to convince NASCAR to NOT allow anything morep owerful to reach crazy speeds. It worked and IIRC, it was scrapped and melted down.

 Wasn't the ball stud HEMI a different motor than the DOHC Doomsday HEMI?  And yes it was called the A-925 engine. 

[Ghoste]

Yes, the ball stud was a later experiment.

Check out that Distributor "spacer" on that 925 DOHC set up to clear the T-belt.

OMG!!!! Dare We Call it a Big Block Chevy Hemi[Ball stud] since it had "porcupine" Valve arrangement? YIKES!

Yes, the ball stud was a later experiment.

The Ball Stud was coded the A279, and yes Arruzza wound up owning it, design, parts, etc. A well done story appeared in the MCG in August 2006. Sorry I have no way to reproduce the article here, or a link.
