Honda CB350 Race Engine Build- 48HP

Sharing my build of a 1970 Honda CB350K full race engine. Techniques shown include engine assembly, piston measurement, valve spring setup, cam timing, dyno test and more. This is not a full tutorial on everything involved with an engine build. It does not show porting, valve seat installation, oil cooler setup, larger cylinder studs, or special valve seats. Motorcycles are dangerous.
