I'm right at the beginning stages of a long rod 225 buildup now. I think 250 HP from a naturally aspirated slant is a stretch........for a STREET driven slant, but it certainly can be done and then some. They just get really radical at that power level and above. I am giong to be perfectly happy with whatever mine ends up being. I project 200-220 HP. And that will be snappy in a 2650 pound 1963 dart with a 4 speed overdrive and 4.30 gears. Something fun to drive is what I am after. If it gets too radical, it will be fun to drive only for a short time....then it will become a chore.
