what was the highest horsepower 396 produced by GM?

Answer 1

402 was actually a bored out 396 but the 396 tags were put on some cars! 425 horse seems to be the highest reference but now you have to learn about changing old HP to NET HP!


396 and 402
The 396 in³ (6.5 L) V8 was introduced in the 1965 Corvette as the L78 option. It had larger bore and stroke at 4.094 in by 3.76 in (104 mm by 96 mm) than any previous small-block and produced an amazing 425 hp (317 kW) and 415 ft·lbf (563 N·m). This version of the 396 was equipped with four bolt main bearing caps and was very comfortable with being operated in the upper 6000 RPM range.

Introduced in 1970, the 402 in³ was a 396 in³ bored out by .030 in (0.8 mm). Despite the fact that it was 6 c.i. larger, Chevy continued marketing it under the popular "396" label in the smaller models, and as the "Turbo-Jet 400" in the full-size series.
