Approximate horsepower

As long as the compression is up to snuff, you'll make a massive amount of tq in the 2800 to 4500 range. You will be power limited upstairs, but if this is mainly a street car, i'd run no more then 3.23 gear, a tight 3k converter and cruise,cruise,cruise with the ability to smoke the tires into the next county. :)

As far as HP, i'll agree with ''273'', @5500 ish
