The cylinder heads are the same from the Visible V8 @ 5000 RPM 1-4 videos, with a new valve train geometry to correct a valve float problem above 5300 RPM.
The rods, pistons and crankshaft are from the Visible V8 @ 5000 RPM 1-4 videos. In this test, the generator bracket came loose about 6000 RPM. The Crankshaft sheared off at the 3 and 4 rod journal.
