Lets talk about what you want to see in a Gen III aftermarket Block?
With all the lifter issues that have happed with the 3ghemi, it might be a good idea to design the lifter bores to provide better lubrication to lifter. When you look at lifters that have been in use for a while, there are pretty noticeable wear marks on the lifter body. However, the part of the lifter that could use the most attention would be lowest part of the lifter, the roller. The vast about of lubrication for lifter occurs much higher by the lifter oil gallery. There a lot of strong feeling about the ultimate cause about lifter and cam failures, but increasing a small amount of lubrication to this area sure wouldn't hurt.
