The engine lineup was the most confusing it had ever been. Depending on where you lived, you might get a Pontiac, Chevrolet or Oldsmobile mill. There was a separate 49-state engine lineup, as well as a California and high-altitude lineup.
The base GP engine for '77 was the new 301 Pontiac V8. It was a short-deck whose basic block dimensions were quite similar to the old 303 Trans-Am race motor, though it was not nearly as beefy. Its deck was 1.12 inches shorter than the 350 or 400. Connecting rods measured 6.05 inches—vs. 6.625 inches for its larger brothers. The new engine shared the same 3-inch main journal diameters as the 350 and 400. The block, heads and intake manifold were very lightweight castings, and the crankshaft only had eounterweights on each end in the interest of weight reduction.
The result: The 301 came in at a very svelte 452 pounds, or about the same as Buick's 231 V6! It produced 135 net horsepower at 3800 rpm, with 240 lbs.-ft. of torque at 2000. While not earth-shattering, the power level was similar to other 5-liter V8s of the time, and it had the weight advantage. Less weight is the same as more horsepower.
Next up the option ladder was the "5.7-liter" V8. Depending on the plant, the time at which the car was built and the zone to which it was delivered, a GP might get a 350 Pontiac, a 350 Olds or a 350 Chevy.
There were a couple of reasons for this. The first problem was that the 350 Pontiac would not pass the stricter California and high-altitude emissions standards. In its place, Pontiac substituted the 350 Olds engine.
Since the Olds engine was cleaner-running, it was in demand. Soon, there weren't enough to go around—Oldsmobile didn't even have enough for its Cutlasses. So, the Olds 350s were replaced with Chevy 350s.

Il serait très possible que ce soit un 301, car mon beau-père possède un hot-rod monté sur un frame et mécanique de grand prix 1978
