It was earlier than that, I think...like 72 or 73...if not 71...
However...it is also widely held that many companies underrated their
highest engines then by a good amount for insurance purposes.
This seems to be held up by the fact that some magazines have, for the sake
of it, built up to original specifications, classic king-of-the-hill engines
like the 454 LS6...and dynoed them...and with SAE Net, (previous was SAE
Gross - they could run the engine with no engine-driven accessories
(external water pump even!), pull vacuum on the exhaust, etc etc...wasn't
very representative of what went in the car...SAE gross specifies it as
having to be exactly as it's installed in a car) the engines dynoed out to
very close to what numbers they were given in their day.
GM certainly pulled quite a few tricks on their truck line, given my
mostly-original but somewhat-hopped-up 1970 GMC with a 4bbl 350 was rated at
255hp, yet my fastest 1/4 mile shows a mere 191hp after some tweaking...and
I'm running a slightly better carb, more open intake and exhaust, and a
bigger cam than it came with back in '70. =P
