factory horsepower

How much horsepower does a stock 350 with a 4 barrel Q-jet in a 70 pickup have?

Chiltons states 225@4600 hp and 355@3000 lbft. These numbers are SAE, reduce by 25% for NET the standard for '72 and after. I think todays crate motors from GM are SAE ratings also.

My 70 owners manual gives these numbers: gross hp 255@4600, net hp 200@4000. Torque gross 355@3000, net 310@2400. That's w/ comp ratio of 9 to 1.
