Rob, as for the cam lobe, can't that be moved over as well? I'm not sure how much room there would be before getting in the way of the other lobes. Just thinking, if you could machine the block, make a custom cam, and use their new lifters, you would have better overall geometry and a lighter assembly as well. It could be marketed as a TIGER Block option. Wonder if Allpontiac has any raw forgings they would donate to the cause?
