I have to agree. Really looking forward to the rest of the mods. Rocker Arm geometry, manifolding, ignition, and so on. Neat stuff, Rich.....

Some pictures from today

We machined the areas around five of the head bolt holes to make sure they were flat. Some of the holes had to have a drill run through again to make certain they were clear of weld. Then we tried it on the block.









Once we knew the head fit again, we started on the spacer for the intake side. It is going to adapt the the fuel injection intake and cover up the part of the block the head doesn't cover.

First we made a pattern off the head



Rich blued the aluminum selected for the job at hand.



Then to the mill







We drilled some 7/8" holes and that was it for the day. Rich gets tired watching me fumble around at his mill so he needed me to stop.

I suspect if he will post some pics later this week.

wow what great STUFF!!!!!!!!!!!!!!!

When someone says they built an engine, refer them to this diary

and make certain that have the real concept.

Great work fellows.

Glenn, few will tread here - the new frontier of the Ozone Rangers.

Fewer will succeed.

But Rich has been here before, come back with reconnaissance, and signed on for another tour.

This is going to work.

And probably pretty damned well.

Very few Chris. I am lucky to have someone like Rich nearby. Metal wizards they are!@

Would we call this project a head job?

Jeez, I hope there's no plans for a supercharger.

Reminds me of the time my luddite boss at the rod shop got on our then new internet, typed in "blowers" and hit the I AM FEELING LUCKY tab...................took myself and a pal 3 hours to take all the Russian and Eastern European drivers and spyware off the computer! Boy did he get to see some things before he finally unplugged everything!

And this is the idea of what the spacer plate will look like. Needs more chips out of it.

Rich has a Hilborn injection unit for a Chrysler race head.....we think. It will be modified slightly to work on the head. The ignition is a Rotophaze distributor that Rich already has from when he started this project. The Edelbrock head uses SBC roller rockers, we will need to clearance some of the push rod holes, but I already have the roller rockers. The head was chosen because the cylinder spacing and the location of pushrods and head bolt holes was basically as perfect as you could hope from a head designed for an engine made probably 50 years after the 26 dodge. It is a Chrysler magnum head. We need lots of machine work, pistons, and pushrods. We will need to make the exhaust headers. But, then we put the engine back in the car and try to fire it. Easy, just lots of time and money.

Just a thought - and bear in mind, this is from a guy who was fighting for every last CFM of air I could find.

I understand the need for the plate, I would consider the effect it might have on airflow on the short side radius going into the combustion chamber.  Perhaps raising the slot in the plate might give you better flow.  I'd look at the Edlebrock manifolds that work well with this head, and try to emulate the flow pattern - you won't be far off.

But on the other hand, this thing would take a major mistake to choke it off, and I don't see you two making major mistakes. 

Stellar workmanship.

[RichFox]

Fitting under that hood is also a concern. So the extension ports flow down about 5 degrees to meet the head. The Edlebrock intake ports are nothing to write home about. CNC milled for the first 3/16 maybe. But the stock Dodge Bros. only had one intake port and that was on the opposite side from the valves. So it's got to be an improvement.

[zenndog]

Here is today's progress. We worked on drilling the mounting holes for the intake adapter plate.

First Rich marked off where the head bolts were in relation to the ports with red tape



Then after some discussion we marked and drilled the holes.





Rich plans on drilling and tapping the holes in the head tomorrow. We actually drilled the holes in the plate with a #7 drill so the holes in the plate can "guide" the drill for the holes in the head. Once the head is drilled the holes in the plate will be opened up so the 1/4-20 cap screws will fit.

This is absolutely beautiful. I'm glad you didn't quit.

Art and ingenuity in metal.
