i was just wondering how much power can i really pull out of a 225 slant 6 in my 72 demon... where can i find parts for it and how much is it going to run realistically....
It depends; there are some normally-aspirated '6s running 11.50s in 2,300-pound car (that takes about 300 HP), while the turbocharged cars can run 127 mph in the middle 10s with about 440 HP.
These numbers are from an online calculator that is probably not the most accurate way to measure horsepower, but will get you some idea of those engines' output.
