rsimoes,
Yes the GT engine is an aluminum block with a blower. But the Prototype engine was an iron block. Then when Ford gave the go ahead then a new block was designed for the project. Just read the SAE paper that was posted earlier. The GT engine was basically designed from scratch for the application.
MRMAX,
I had nothing to do with the the Spray Bore Technology while I was at Roush. The group I was in at Roush only worked on the 03 Cobra, Lightning and GT projects and some other powertrains. I no longer work on these small engines, I steped up to some real high horsepower engines (50,000+ Horsepower). But I do know about the technology and know that it has been used successfully for a long time. I think the argument between sleeves and coatings is as big as the BB vs SB arguments.
Regards,
