:Ive been wondering why is it that the '75 250c.i. engine only puts out 72 horsepower as a factory rating? this is actually the least horsepower year this engine/trans combo had. i was wondering if that is because of the carb setup that year or something else, because i have a carter yfa and ive seen other 250s with diff. ones. and it only seems logical that if the carb is restricting me then i would be able to upgrade to the setup from a different year and gain hp. think it'll work? ..The factory changed the way they reported the horsepower figures in 1972, from Gross power(without accessories attached) to Net power (with all operating accessories) as installed in the car. There are other changes due to the increasing EPA rules to improve air quality as years progressed. It's not just a matter of changing parts on the outside, for easy power increases, to a stock engine.
..Hope it's a help in understanding the factory ratings. This engine can be upgraded in power if enough mods are done.
..For more info,look up the Clifford Performance website. They are a Ford six equipment co..
Best to you,Ken
