I can't even get myself to answer certain people, but there was a time when engines boasted GROSS hp, and in later times (like after 1971) they were measured in NET hp. The LA 318 produced 150 hp in 1972 when using NET hp. The 318 magnum produced 230 NET hp. And the LA torque fell to 260, while the magnum had 295. so much bad info gets posted... lol But I can't play anymore.... chinese torture LOL Dan, I wish you all the best buddy :)
