Here we have the R07 engine block. While it has already proven stronger and more reliable than its predecessor, it looks like something that came from the moon (to the more traditional Chevy crowd). Will this design be mimicked down the road for production use? We're not sure. However, if it works on the highest level of abuse during race conditions, why not the daily rigors of street driving? Notice the offset lifter bores, which are bushed and honed to the tightest of tolerances. This helps eliminate the lifter from side-to-side movement. With a redline of 9,800 rpm, lifter movement can become a concern.
