Enough snow. I'm from California. If it snows here I'm calling 911. But I do have a picture of taping for Hilborn nozzles. These throttle bodies were for down nozzles.

Rich;

What is the thread on Hilborn nozzles-- 1/8 NPT?

Yes 1/8 NPT or 1/2-20 if you get the straight thread type.  I am lucky that the casting i amusing is about 5/16 thick where I drilled it. Plenty of bite for 1/8 NPT.

We cut and welded the valve covers today









In the picture you can see that Rich brazed on the tubes to weld the headers to.

It has been a while since we posted, at least on this thread.

Rich posted the following under EFI questions a couple weeks ago

http://www.landracing.com/forum/index.php/topic,14831.30.html





Rich made those aluminum inserts on his lathe using a corner radius tool from his mill to cut the radiused throats in three cuts. Pretty cool.

In other fronts, two months ago Rich noticed the head cracking where the spacing plate was welded in. I took it and had some friends if mine weld it. They did a great job but it took a while for me to co-ordinate it. Pics.......









After the weld repair, we had some light machining to go over. I actually took it to a local machine shop to mill the exhaust flange mounting area, and Rich and I cleaned up the header bolt bungs that received a little touch up

The next step after the head was back was to check the valve clearance with the Pistons and take a look at how the pushrods line up. This was two weeks ago.

We put in the valves on number 1, using springs from an inline 6 that space the rocker arms, instead of the actual valve springs.




We put on a head gasket Rich made for a possible flat head version of the dodge.



Rich removed the lifter cover.

Glad to see you caught the leaks early. 

It's never been done before, but your thoroughness on this project tells me it's going to succeed.  cheers

Target date to get it up and running?

So two Saturday's ago we set the head on and checked the valve train geometry

Here are the push rod clearance holes as machined from Edelbrock



We knew we were going to need to open up the push rod holes.

But here is where I stopped taking pics that weekend. We clearances the holes to .625. We still had some rubbing and the hardware for the plugs Rich had made for the stock exhaust ports in the block was also in the way. We finished off the day slightly discouraged. When I got home Rich had sent an e-mail stating there were issues with the exhaust valve hitting the piston, and since the Pistons were turned down already, there is no more material for valve pockets. That meant new Pistons would be needed, custom of course........

Fast forward to this weekend.

We put the head back on and took a look again

The exhaust valve is not hitting the piston-positive.

I rechecked the valve train geometry, and marked where additional clearance is required

Here are shots from Sunday, 4/19






After this fine butchery........oh, I mean precision machining. The pushrods are fitting much better, the pushrods guides will need to be cut and re welded to make them wider. I popped through to the water jacket in one spot, that will get a JB Weld treatment.

Here are shots of the valves in place, the misalignment is cause by the push rod guides, which will be rectified when the custom push rods arrive.





There is one intake valve that rubs the cylinder wall. All the intake valves will get about .02" shaved off the OD of the valve head.
That is it for now. Up to date.

Zenon, the guy who owned the aluminum head, took it home to weld the valve cover and never came back. I had surgery that slowed me even more last new years eve. I have spoken to Zenon a few times, but I guess he lost interest.
