Cobra Make, Engine: Kirkham Motorsports, with a prototype wet sleeve billet aluminum engine block that I made

This is Cindrich here. I heard my name getting tossed around here, so I thought I'd chime in.
The FE block is running well. I had some issues with the head gaskets leaking, so I made some copper gaskets. They leaked also, so I flared the edge of the gasket around the cylinder and finally got a good seal around the combustion chamber. But it leaked water from between the head and the block. So I then added "The Right Stuff" gasket sealer to the copper gaskets, and its all good now.
The engine made 630 HP and 580 foot pounds of torque. Not bad for a home made engine! It seems to pull really hard at 5000 rpm, more than any other FE I've driven that was built with the same specs.

We will be making more of them some time, but not sure when. We may make the same thing as before, but we did run into some patent issues with Darton with the sleeve we made. So at best we will need to do a redesign of the sleeve. We also may make a open deck 427 block. i've been midway through programing it, then got pulled off it to do other things.
Its true we will be making a 302 billet block soon also, but I can't know exactly when we will be able to get to it. We have a lot of customers cars that need work before we can make time for the 302 block.
I can tell you that it may end up being a open deck style block, with a standard sleeve. 4 bolt mains and a one piece main cap girdle.

As far as a billet block verses a cast block, its stronger, and lighter (assuming the guy who drew it knew what he was doing).

Does anyone really "need" a billet block? No! But they are cool as hell!
