Someone has actually done this! :shock:

This is serious. I touched it and took a couple pictures with my cell phone!

No, it isn't going to be in the Edlebrock catalog anytime soon. :lol:

This is a one off, custom deal whittled out of a solid block of billet aluminum by one of our fellow Slant 6 racers using a CNC machine. :D

Flow numbers are a secret that he wouldn't share with me, but this head is 90% complete and bolted to a Slant 6 block along with the custom intake and header. Plans are to have the completed engine on a dyno and then on a dragstrip early this season. :shock:

I'll post the "spy shots" he let me take shortly. :wink:

I'm no machinist, but how did he manage the water passages if it's machined from a solid block? Surely he must have cast them in before milling the exterior/ports/etc...

Haha yeah I've seen machines like that in action... still seems amazing that the internal concave passages (with such small openings) could be done that way too! :shock:

You can also drill long intersecting passages from outside, then put in expansion or NPT plugs to seal up the water jacket.

Skeptical and not at all excited yet...

From the initial text, the head will be used on a drag race engine so I doubt that water jackets are part of the design. Over in the (big) Ford inline camp, they have a VERY EXPENSIVE billet head that comes from Allen Johnson and it is solid billet with no jackets and exclusively for (comp class) drag racing.

One thing that I admire about the Big D - No beating around the bush! What ya see is what ya get - like it or not -don't make him no nevermind. One could call that integrity. 8)

Told ya I wasn't foolin'!

Yep, drag race head with really big ports. I have a few details about it and got to see under the valve cover, etc.

Don't everybody go buggin' poor Howard to death about it neither. Just let him get it finished and out to a track first.

He promises that if it works out like he hopes it will he will bring it to some Slant 6 races this year! :shock: :D

(He also said that Barry Harrison had better bring his "baby bottle" and a case of beer! He wants a re-match. :twisted: )
