Ken I have to agree with Don. I can't manage to properly seat a front seal, let alone design and build an engine. :eek: As always, thanks for sharing this process with us. It
s great to watch your ideas become realities.:D

Pat-What if you run into porosity pockets when you bore the hole? Do you have any suggestions on the studs if we do run into some tight ones? I'm going to finish taking it apart soon and get it cleaned, I would like to remove them first.
Steve- You just learn from every problem, you know how to put a seal in properly now, I bet you won't forget. :D
Ken
Ken, the stud can be burned out with an EDM...if you can find a machine big enough to hold the block. Same as burning out broken taps. You can use a copper-tungsten
electrode....on the corroded studs, the threads may not be in good shape.

hi ken is it just the way the picture look or did these engines have the same size valves both intake and exaust kinda looks like that in the photo....ted
try bees wax on the block heat up the deck and let the bees wax wick in you my have to do it more then one time to bad you did not live close i would like check it out if you lived by me i have a 500 gal hot tank with the good stuff in it will eat some rust . any one has one out were you are or buy some of that rust eater flip the block upside down in a tray and let the rust eater work from the deck and the under side to .on the porosity it would be nice to have a junk block to cut on .i think if you cut the seat s out and use a bowl hog that tapper will help or just get the block up on a mill and go in on the angle with a end like a 7/16 mill and take what you just need if you use a bowl hog you should center up on a pilot that plug in the guide holeQuote:

Ted- Yes the valve diameters are the same, I'm going to change that. I think they did that just to do everything they could to get it to breath.
We have got a lot done, I know the valve angle we are going to use, valve diameter and the geometry for the rocker arms.
We wanted to make sure that our drawings so far were accurate. So we took the drawing to our lazier cutter and had him cut us what looks like a very thick head gasket. Now we know we have everything in the right place, water passages, head studs and bore centers.
The next thing is the drawings for the valve train and intake and exhaust ports.
Just a side note on this, usually when you draw something like this you just draw a center line down the middle and draw one side then make a mirror image for the other side. Not the case with this engine!!
Ken
Ken I don't know how you do it. Work, then the 32 project and the Ardon all at once. Keep posting. Also what block are you using? Did ardon have a v-12? or is the block from something like a Jag? Hope I'm not repeating a question here!:3dSMILE:
Looks like one of the old Lincoln V-12 blocks, a very interesting engine considering when it was designed!!!!!Quote:

The Ardun project I work on it when I'm at work, that's not to time consuming for me. I'm just designing it, the real time comes in the drawing department, I can't do that. Then I go home and work on the roadster. My friend works nights, he's off for veterans day so we will pull an all nighter, the clock is ticking :eek: :eek:
Ken
That's certainly some very nice work Ken, ain't them laser cutters just the neatest thing since sliced bread????
Been awhile since I worked on a V-12, but I sure do remember what a booger it is to do work on the distributor while it's still installed!!!! Just looking at the surface and layout of the block shows that their is no room for error in designing any of the components for an OHV conversion..... I'll bet a CNC man could start a whole new career writing the program to make a billett head for it!!!!!!!!:LOL: :LOL:
Another outstanding project Ken, maybe this is the one to plan ahead for an entry in the GNRS. Just a thought.
Mike
Ken, given your history with bikes this might be some inspiration............
That is one double throw down super kewl scooter you found a pic of Uncle Bob!!!!! Some day I'm going to get caught up and start me a trike project with some sort of outlandish engine, the V-12 would sure do it!!!!!
how about a donovan 734 i know a guy that will sell one :DQuote:

Bob-Wow, never saw that before, thanks.
Pat- My theory is,If some is good, more is better, and too much is just enough :LOL:
Here are some preliminary drawings on the heads.
Ken
looks good have to move the spark plug in front of the two valves .i like to see the intake runners lay out. are you going to tube the intake push rod and run it thru the port . you going with the t@D /jesel rocker stands type . i hope you do not mind here is one of my heads i had to show someone i have alot of time in them but nothing like you are doing :D
Pat-Nice head, you must have a lot of time in them.
I'm going to make it a swirl port design, so the intake runner will actually clear everything. Where it gets tricky is the location of the intake and exhaust valves. They swap positions depending on the location of the head studs so I can keep the runners close to the same. The cam grinder is going to love me :eek: The rocker stands are going to be a little different, I will show that next with the port design.
Ken
about the cam are you going to make your new steel core for that .thank on the heads . i will have some time in the engine when done the block is just about done i hope to have the the two titanium crower rods or just may have some steel olivers rods made up some of the same stuff your doing i just did not have to make the headsQuote:

Ken
Certainly is going to be an interesting engine Ken! The mix of old and new technology is always challenging, but your project is way beyond that!!! I did have to uncover my Ford V-10 and take a good long look at it the other day.... Just haven't came up with the right home for it yet.
I'm really looking forward to see the work continue on your V-12, it's going to be a really unique centerpiece for a project car!!!!
Is this the set you're giving me for Christmas this year, Pat???? Superflow should be there any day now to set up the new engine dyno I bought you for Christmas!!!!!!!:rolleyes: :rolleyes:Quote:

Pat. those heads look great.
BradC
BradC- I will post this this week so you can see that.
Ken
Here is the spark plug location and the intake port.
Ken
Thanks Ken, Can't wait till you've CNC them and see the finish pieces. How are you going to seal the 2 halves together.
BradC
BradC-I'm not sure we are going to make them out of billet. I have been talking to a few people that may be able to cast them using some low cost tooling.
Here is the latest, they are almost done. Not the ideal Port configuration but snaking around everything didn't leave much room.
Ken
You've come a long ways on the heads Ken! The drawings are really great!
hay ken if you cast about 10 million sets the price per unit should be down to the point I could afford a set put my name at the top of that list L.O.L ted
what cr do you think your going to come up with ? if your going to run a dish pistons . why not run a hour glass chamber in the head ? the head looks good
Well, you know the old saying 1 step forward 2 back? That's about where I am. Don Ferguson (the guy who makes the Ardun motor) came by and brought me a V8 60 Ardun style head and valve train.
I was showing him how far along I was on designing my head for the 12 cylinder. He looked at it for a few minuets, and told me it really looked nice, it should make good power and be able to turn some good rpm. Then he says,"I thought you wanted to build a Ardun style head?' I thought for a second and said, "Your right, that's what I want."
I got in a hurry and started making things easy instead of what I originally started to build. So I'm starting over, and am going to build a brand new
1940's style head! Damn :CRY:
Here are a couple shots of the V8 60 head.
Ken
Here is a size prospective.
Ken, is there a way you can angle the plugs in so they're closer to the center of the chamber?
