Sorry, no...that's the 302 at the flywheel.BUT...after like, 1971 or '72, engines were rated differently than before that year. Before, engines were rated with NO accessories on the engine. Just the engine itself was tested, thus the higher numbers. Thanks to the government, in '71 or '72 (I can't remember which year), engines were tested with all accessories on them...smog pumps (where applicable), alternators, etc. At least, this is what I've been told before. So in theory, the IIs engines could produce as much power as it's predecessors. Just different ways of testing. ------------------

Nope net horse power at the crank. Not an expert on this subject, but here's my understanding. Gross HP: Horse power the engine has with no waterpump, alternator, power steering pump, AC compressor and airpump. (measured at the crank). Net horse power is taken at the crank with all the accesories attached. 139hp is not too hard to believe when you figure in a car that weights 2800lbs and has a V8 does the quarter mile in 17 seconds, ouch! No problem just add a free flowing exhaust and a new engine and carve 3 to 6 seconds off that time!------------------
