Yes it is - stock GM parts! This is one wizzy engine. Some folks in the know (not me) claim that with bigger camshafts, minor exhaust port work and a set of headers its good for 100HP/hole.
There are some things that are a pain though - all the fittings are metric and all the critical fasteners are torque to yield crap.
