David,

Alfa engines have been wet sleeved for generations. Cast Aluminum blocks with iron sleeves. If I remember correctly the liners had flanges toward the bottom that rested on an O ring against the block. They were held in place by the clylinder head. If assembled correctly it was bullet proof to 9000 rpm on the street, if not it wouldn't last a week.

A wet sleeve the outer surface is part of the water jacket around the cylinder, this helps speed up heat transfer between the bore and coolant. With coolant indirect contact with the cylinder sleeve corrision CAN be a problem. It can even insulant the sleeve from the coolant which reduces the main advantage of having a wet sleeve at all. The walls on a wet sleeve are thicker than on a dry sleeve, they dont have the same support from the block as dry sleeves so they depend on there wall thickness. In diesel engines vibration caused by combustion can cause CAVITATION this damage appears similar to corrosion and can eventually destroy the engine. Now that said i understand wet sleeving is a viable option, just dont see it too much in big block daily drivers. (I DONT DOUBT THE KIRKHAMS FOR ONE SECOND)

That sounds like most things in life. If an FE isn't assembled right it won't last 2 minutes

Milling the outside port for the main oil galley. We eliminated the lower oil remote and will plumb the oil cooler hoses directly to the block...why have extra parts?

Getting ready to do the final pass on the cylinder bores with a boring head.

We had to do a little custom work on the boring bar to make it stick out past the boring head.

The bore is quite deep for the sleeve.

Here is the YouTube video from Kirkham Motorsports University. Here we show you how we took a solid, 386 pound block of aluminum and machined it into a 427 FE engine block.

David, impressive video! After the R&D is competed, will this block go into production? I hate to ask, I'm sitting down, how much$$? Peace, Darren.

Glad you liked the video. I think it is my favorite one to day. Thanks for the ideas and the push to help us get this going. (We will have another Flip-Top video tomorrow

We don't have a price yet. We don't even have a running engine yet

We are hoping to have it sell for less than the Shelby or Pond block...

Wow! 17 percent of the original chunk of aluminum left!
Just goes to show the other 83 percent is a waste.
Kirkham only keeps what's necessary to produce power.
Can't wait to see the dyno run and final pricing to see if I can fit it in my budget.

Congrats Kirkham team! Another project done with excellence.

Thanks for the kind words. If it doesn't make the car go faster...we left it out.

The other 83 percent isn't waste--it is on its way back to Alcoa to turn back into a block some day

David


ps. we have a bunch of parts here for you. I'll call you tomorrow.

Are you going to etch in the timing marks for accuracy?

"We don't make mistakes...we have happy accidents."
Or... schedule-altering learning experiences. At DARPA, we called that "research".

Our friends at KSC and Thiokol used to call them VLE's. Sounds benign until i give you the code: Very Large Explosions.

Absolutely facinatin' work, chappies. Dobbers'up! Wet sleeves forever. See Alfas above.

If we could only take that milling machine to DC. 83% waste seems about right.

i could live forever on your and Tiger's throw-away.

It really is quite light. Where would we etch in the marks?

Thanks for the kind words. What Shingo taught could easily apply to DC. I doubt there are many people there who want to listen, however. Sometimes I wonder if it is a feature--not a bug

This thing is gorgeous! As you said quite a bit different from what you originally envisioned. Wet sleeve, webbing in the lifter valley, I’ll be quite interested to hear what you learned from the F1 engines that you didn’t already know.

With cast iron sleeves and the bottom to go, what do you expect the final weight to be?

Again, that thing looks so good I can see glass windows in the side of the engine bay just to show it off, that or perhaps a lot of flip tops.
