That’s all they’ve posted so far Mike but by the looks of it, it’s not a skirted block so I would guess no cross bolts. We’ll see.

Yes, your right after a look at the rear shot of the block. Possibly, they have some sort of mid-plate in mind that would incorporate the main caps somehow. Just having the caps bolted to the pan rail on the outside doesn't offer much strength to the lower end, unfortunately. They are smart guys, I assume they have something in mind for the bottom end.

Tom, I just now saw the pic of a production casting? Looks right out of the mold. How cool is that. Way to go.

I asked about why a billet SBC block was not made with a skirted block and I got flamed.



Darrin Morgan actually replied and said it was not need up to about 8500hp.



I just think it makes sense but I guess the experts disagree.

I would like to discuss this with Darin Morgan further. Obviously, with his general love of the BBC based powerplants, he has lots of experience with making a non-skirted block live at high RPM's and HP. But conversely, I don't know of a single V-8 modern engine design in the last 25 years that is not a deep skirted design from any manufacturer. Ford modular, GM LS, Chrysler Hemi, all deep skirted. This design uses more material, is much more complicated to cast, is heavier, and cost more to produce. Why would all of the big three do this if their was no benefit? It's a head scratcher.

May I ask where you were discussing this with him? An open forum like Speed Talk? I hate to call him about little stuff like this. Thanks.

I correct the HP figure 5500.
