I have got the parts to put a 496ci motor together to go along with my 468ci. A friend of mine put together a 496 for his dragster over the winter, has all eagle stuff and je pistons, comp 748/748 roller cam dart 360 heads, super victor intake and apd 1050 alky carb and we guess it makes around 750hp. It has been 7.87 in his 1918lb swingarm dragster.
