horse power was faked by ford in them years,,because of regulations,,and they got caught and heavly fined for it,,,,,71,,too 1973 351's are the fastest stock small block made in production,,,13:33 in the quarter,,mine is barly over stock,,been rebuilt once,,gots 11;to1 ,,pistons in it,,but it had them stock anyways,and took off emissions crap
horse power in the 71 model mustang mach 1 is dyno tested at 330 horses,,with 370lb torque<~~thats with boss motor package,,they were big cars,,but fast,,just long as you tear most of the emissions crap off them,,,and make sure its a 4v model with ram air,,and you would be surpized how well they corner
i raced my cousins rx7 with a nice built custom rotary,,and he couldnt hang with my cars,he said in the corners he could stay with me and out corner me a little,,but its like racing a fw 190 against a spittfire,,sure the spitt corners good,,but doesnt do him any good unless he is on a circle track,out of the corners i would just walk him with power
you will find alot of horse power faked during the 60's and 70's,,,heck they tried to say the 429 boss,only had 425 horse power,,,,and now when they dyno test them cars,,they read out too about 500,,too 550 horses,,,,same with the hemi,,said it wonly pushed 425 too,,but more like 500,just because they were car companies they could fake it past the goverment just to give them a edge on there rivals,,,most books i read on mustangs 71 too 73,some will say,,150 horses,,,some will say,,330,,some will say,,250,,,and from what i read they said,,never beleve the old cars horse power ratings,,they were all faked,,most allways they pushed atleast a 50 too 100 horses more than stock
